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
