I followed the example of drivers/s390/,
per Linus' suggestion.

The other place that seemed to suggest itself was
arch/x86/drivers/, as we already have:

arch/um/drivers/
arch/sh/drivers/
arch/cris/*/drivers/

These are vendor-specific, aka "platform specific" drivers
for various x86 platforms.

> What is wrong with the current location under misc/*?

mostly that it "misc" means nothing at all...
Indeed, misc should probably be deleted for this reason...

is there an example besides lguest/x86?

+
+	  Compal FL90/IFL90
+	  Compal FL91/IFL91
+	  Compal FL92/JFL92
+	  Compal FT00/IFT00
+
+	  It adds support for Bluetooth, WLAN and LCD brightness control.
+
+	  If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.

+	select BACKLIGHT_CLASS_DEVICE
+	depends on INPUT
+	  ---help---
+	  This mini-driver drives the SNC and SPIC devices present in the ACPI
+	  BIOS of the Sony Vaio laptops.
+
+	  It gives access to some extra laptop functionalities like Bluetooth,
+	  screen brightness control, Fn keys and allows powering on/off some
+	  devices.
+
+	  Read <file:Documentation/laptops/sony-laptop.txt> for more information.
+

+	---help---
+	  This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
+	  support for Fn-Fx key combinations, Bluetooth control, video
+	  output switching, ThinkLight control, UltraBay eject and more.
+	  For more information about this driver see
+	  <file:Documentation/laptops/thinkpad-acpi.txt> and
+	  <http://ibm-acpi.sf.net/> .
+
+	  This driver was formerly known as ibm-acpi.
+
+	  If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
+
+config THINKPAD_ACPI_DEBUG
+	bool "Verbose debug mode"
+	depends on THINKPAD_ACPI
+	default n
+	---help---
+	  Enables extra debugging information, at the expense of a slightly
+	  increase in driver size.
+
+	  If you are not sure, say N here.
+
+config THINKPAD_ACPI_DOCK
+	bool "Legacy Docking Station Support"
+	depends on THINKPAD_ACPI
+	depends on ACPI_DOCK=n
+	default n
+	---help---
+	  Allows the thinkpad_acpi driver to handle docking station events.
+	  This support was made obsolete by the generic ACPI docking station
+	  support (CONFIG_ACPI_DOCK).  It will allow locking and removing the
+	  laptop from the docking station, but will not properly connect PCI
+	  devices.
+
+	  If you are not sure, say N here.
+
+config THINKPAD_ACPI_BAY
+	bool "Legacy Removable Bay Support"
+	depends on THINKPAD_ACPI
+	default y
+	---help---
+	  Allows the thinkpad_acpi driver to handle removable bays.  It will
+	  electrically disable the device in the bay, and also generate
+	  notifications when the bay lever is ejected or inserted.
+
+	  If you are not sure, say Y here.
+
+config THINKPAD_ACPI_VIDEO
+	bool "Video output control support"
+	depends on THINKPAD_ACPI
+	default y
+	---help---
+	  Allows the thinkpad_acpi driver to provide an interface to control
+	  the various video output ports.
+
+	  This feature often won't work well, depending on ThinkPad model,
+	  display state, video output devices in use, whether there is a X
+	  server running, phase of the moon, and the current mood of
+	  Schroedinger's cat.  If you can use X.org's RandR to control
+	  your ThinkPad's video output ports instead of this feature,
+	  don't think twice: do it and say N here to save some memory.
+
+	  If you are not sure, say Y here.
+
+config THINKPAD_ACPI_HOTKEY_POLL
+	bool "Support NVRAM polling for hot keys"
+	depends on THINKPAD_ACPI
+	default y
+	---help---
+	  Some thinkpad models benefit from NVRAM polling to detect a few of
+	  the hot key press events.  If you know your ThinkPad model does not
+	  need to do NVRAM polling to support any of the hot keys you use,
+	  unselecting this option will save about 1kB of memory.
+
+	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
+	  unlikely to need NVRAM polling in their latest BIOS versions.
+
+	  NVRAM polling can detect at most the following keys: ThinkPad/Access
+	  IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
+	  Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
+
+	  If you are not sure, say Y here.  The driver enables polling only if
+	  it is strictly necessary to do so.
+
+config INTEL_MENLOW
+	tristate "Thermal Management driver for Intel menlow platform"
+	depends on ACPI_THERMAL
+	select THERMAL
+	---help---
+	  ACPI thermal management enhancement driver on
+	  Intel Menlow platform.
+
+	  If unsure, say N.
+
+config EEEPC_LAPTOP
+	tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
+	depends on ACPI
+	depends on BACKLIGHT_CLASS_DEVICE
+	depends on HWMON
+	depends on EXPERIMENTAL
+	depends on RFKILL
+	---help---
+	  This driver supports the Fn-Fx keys on Eee PC laptops.
+	  It also adds the ability to switch camera/wlan on/off.
+
+	  If you have an Eee PC laptop, say Y or M here.
