Is your powerbook one of those who can actually use xmon ? (ie, keyboard
is working ? If it's usb it won't but if it's adb it will).
You probably landed there too late tho, after the corruption happened.
What would be useful would be to see if you can reproduce with SLAB
and/or after backing out the cpu partial functionality.
Cheers,
Ben.
