This is a driver for the ATA controller on the Geode CS5536 companion
chip. The PCI device ID for this device was previously claimed by
pata_amd.c but the PIO timings were not correct. This driver also
works around a bug in some BIOSes that handle unaligned access to the
PCI config registers poorly. Finally, the driver allows fallback to
using MSR registers for configuration on BIOSes that are truly
broken.

applied, after removing the pata_amd patch
I don't typically apply things marked temporary :) but moreover, this is
a bit unusual to do in a driver. Any opinions on simply removing the
PCI ID? what's the installed base like today? do we need to keep the
PCI ID in both drivers?
