hdaps (accelerator) driver for thinkpads

thank you very much!
unfortunately compiling the driver didn't work for me:

*** Error code 1
--------------------------------------------

i had to add

CFLAGS += -Wno-error

to the Makefile to get it compiled but then loading the first module
"thinkpad_ec.ko" crashes my x60t completely :(
i haven't looked any further into the code yet, but it seems that it
supplies the same functionality (sysctls and some mouse/joystick
devices).
i had problems using mtx_lock in the driver i sent. commenting this out
made at least the sysctls work in my version:

--------------------------------------------
$ sysctl hw.accel
hw.accel.data: 2 509 511 57 510 511 57 7 128
hw.accel.aps_sensibility: 255
--------------------------------------------

but the devices are still not usable without resulting in a core dump...
