ok i upgraded my bios (adding a delightful logo to my boot lol)
i messed around with xbacklight a bit, seems to work fine, soon i'll
re-compile my kernel with the new thinkpad acpi...
also, when i loaded the video module, and tried echoing values into the
/proc/ brightness files it created, nothing happened (VID nor VID1)...
could it be because i'm still running thinkpad-acpi v0.16?
anyway, i spent quite some time searching through the mailing list archive,
and i didn't find any way to tie my brightness keys to the acpi video
module... you have the settings lying around perhaps?
