Yeah, I'm not even sure if the cuda driver does anything we can't do on 
mac68k like messing with OpenFirmware. Unlike the old adb driver it 
uses bus_space though. pmu does contain macppc-specific code to find 
the right interrupt to use, for some crazy reason known only to apple 
it doesn't use the VIA interrupt on core99 machines.

have fun
