Ok.

Hmm, so it produces the same ADB sequence as the power button. I  
wonder if there's a way to tell the two apart :/

Then powerd didn't get it, otherwise it would do a more orderly ( and  
therefore slower ) shutdown.

The IO space message is harmless during probing, later on when the  
actual driver takes over it works.
DRM won't work on non-x86.
Finally, your panel doesn't seem to produce any DDC2 output ( the one  
in my iBook G4 does for example ) so I guess I'll add a similar hack  
as I did for the r128 driver - try to get an EDID block from the  
kernel, which in turn obtains it from OF.

I mapped the enter key on the right of the right Command key to the  
right mouse button - close enough to the pad and it's not like that  
key would be used for anything else anyway.

have fun
