That won't do anything, the brightness/volume button keys have their  
own driver now which just posts pmf events. Fn-Functionkey gives you  
the function keys. In OSX there's a setting somewhere buried that  
controls wether Functionkeys or volume/brightness control comes first.  
No idea how to do that in NetBSD, although I suspect it's a bit in  
nvram somewhere where the PMU can see it, since the setting is sticky  
and stays in effect no matter which OS you boot.

This is weird, I'll see if I can reproduce that. Cmd-Fn-F[1-4] works  
for switching virtual consoles here ( order is important though )

Is there an 'EDID' property?

By default F11 and F12 act as middle and right button. You can change  
that using sysctl, see adbkbd(4)
Or you could just use a USB mouse.

have fun
