Stupid vgahw tries to mmap the legacy VGA framebuffer which isn't  
going to happen on a mac. It's also completely useless - they want to  
access it in order to preserve things like the VGA text mode font,  
something we never use.

Hmm, did I forget to support that in genfb_pci? I'll go have a look.

This is weird. Sounds like wsdisplay didn't attach properly for some  
reason. Otherwise the OF font wouldn't even be available.
Do virtual consoles work?

Use /dev/wskbd in xorg.conf - for some reason xorg seems to confuse  
the mux device. Wskbd0 should re-attach to wskbd after being closed  
but for some reason it doesn't always happen :/
