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
