I've done a little testing and have some results now.
I built the ACPI video support as a module and patched it with the
acpi_video_get_next_level patch you sent out in this thread.
I'm using BIOS 2.07 / EC 1.07 on a T60p 2007-93U.
When I boot without the video module, Fn-Home and Fn-End work normally;
tpb gets the key events, shows the OSD, and video goes up and down as
expected. When I load the (patched) video module, video continues to go
up and down, but tpb no longer shows OSD feedback.
The commands "echo {4,5} > /proc/acpi/ibm/cmos" work properly.
Strangely, when using these commands, tpb shows OSD feedback even with
the video module loaded.
I also played around with the ibm-acpi hotkey support. From long ago, I
have a setting of "enabled,0xff9f"; I don't remember how I arrived at
that mask. Changing the mask to 0xffff causes Fn-Home, Fn-End, and
Fn-F7 to start sending ACPI hotkey events. Of course that means that
tpb no longer provides feedback. I'll have to figure out if I can use
those events to support OSD feedback.
