Hi,

2.6.16-rc2-mm1 is running fine on my IBM notebook, but the hdaps module
(acceleration sensor) does not work like I expected:

,----[ modprobe hdaps ]
| Feb 11 21:24:26 nimrais kernel: hdaps: inverting axis readings.
| Feb 11 21:24:26 nimrais kernel: hdaps: IBM ThinkPad T41p detected.
| Feb 11 21:24:26 nimrais kernel: hdaps: driver successfully loaded.
`----

AFAIK the module should create sysfs files in
/sys/devices/platform/hdaps/, but I see only `bus', `power' and
`uevent'.

When unloading the hdaps module, I get a BUG:

,----[ rmmod hdaps ]

Do you need more information?
