it ever arrived on the list at all.)

OK, I did some testing with these kernels:
2.6.22.14
+ thinkpad-acpi-0.18-20071112_v2.6.22.12
+ manually changed KEY_BRIGHTNESSUP & KEY_BRIGHNTESSDOWN -> KEY_RESERVED
2.6.23.8
+ thinkpad-acpi-0.18-20071112_v2.6.23.1
+ uvesafb-0.1-rc3-2.6.23-rc-3
+ manually changed KEY_BRIGHTNESSUP & KEY_BRIGHNTESSDOWN -> KEY_RESERVED
I could get an event in showkey for the mute button when using kernel 2.6.22.14.
This does not work with 2.6.23 and 2.6.24-rc3. Since you were writing in another
email on the list that the volume keys are no longer reported through ACPI this
is probably a BIOS bug.
The power button works on neither kernel. I wonder if it is supposed to trigger
an ACPI event.
For the other buttons it seems that Xorg is interfering. When I shut X down I'm
suddenly getting acpi events for the ThinkVantage button and FN+Space. They emit
events in showkey as well. When restarting X these events are no longer
triggered. Also the FN+F7 combination emits an event in showkey as long as X is
not running.
I have Xorg 7.3 with xorg-server 1.4 installed here and use the nvidia beta
drivers 169.04.
Another weird thing is that brighntess_up (FH+Home) additionally triggers
acpi-event "ibm/hotkey HKEY 00000080 00001010"
Any ideas ?
Thanks,
Jens
