Thanks a lot!
Works OK for me (pb 17" 1ghz), but to compile, i had to s#<linux/i2c-dev.h>#"i2c-dev.h"#
in module_pmac.c and copy lmsensor's i2c-dev.h to the src dir. Also, for
2.6 kernels I have an updated version of the lmu.c at
http://alex.homelinux.net/~alex/tmp/lmu.c
Its detection code is a lot less intrusive, it doesn't probe all i2c devices,
but gets its information from sysfs/procfs. The old algorithm should probably be used
as fallback when sysfs is not mounted.

It would be nice if autoadjust would be disabled when adjusting the
keyboard backlight by hand, and only enabled again after a bigger change
in the environment illumination (no light => bright etc.)
