I guess I wasn't paying close enough attention.  Fn-Fkey does produce
some sort of function string.  Cmd-Fn-F[1-5] does definitely switch


And if you get things in the wrong order:

the key combination "Fn-LCmd" is treated as though the power switch
was pressed.

I'm guesing powerd intercepts this and begins a normal shutdown and
poweroff, but it never completes.  At this point, pressing Fn-LCmd
again elicits a kernel message:

 adbkbd0: power switch pressed, shutting down.

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

(or something like that--it happens too quick) and the machine immediately
powers off.

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

Is there an 'EDID' property?

There is an EDID1 property.  See:


Another curious thing is that "X -configure" says "nothing to
configure" and exits without even a bare-bones xorg.conf.  See:


X runs well enough with its built-in configuration, but throws some
curious warnings about being unable to map IO space, it can't enable
DRM, and a couple of expected modules are not present:


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.

By default F11 and F12 act as middle and right button. You can change
that using sysctl, see adbkbd(4)

Indeed they do. Since F11 has no extra hardware function the Fn key is
not needed.  Since F12 is normally the optical-drive eject button, one
must use Fn-F12 to get the right-button event.

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
