It didn't seem likely to me either, but anyway, I tried 2.6.9, and
my pads still work fine.

Here's the relevant bits of my .config,

CONFIG_INPUT_JOYDEV=m
CONFIG_INPUT_JOYSTICK=y
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_UHCI_HCD=y
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y

What kind of USB controller do you have again?

I'm looking at your lsmod output from the pyddr list, and I see,

  ehci_hcd               29824  0
  ohci_hcd               20864  0 
  uhci_hcd               31112  0 

I don't think you want both ohci_hcd and uhci_hcd (probably keep uhci).

As I recall, ehci_hcd is only for USB2 higher speed stuff, so you might 
turn that off as well, for testing.

Also, try this (before and after dumping ohci_hcd),

 $ ls /sys/class/input/js*
 $ cat /sys/class/input/js0/dev
