        syssrc/sys/arch/macppc/macppc: locore.S

Log Message:
save and restore sprg[0-3] when calling openfirmware
this fixes calling OF_finddevice() with invalid devices,
and as a result fixes booting with -d.
Apparently openfirmware expects persistence of sprg2 and/or sprg3
I suspect this is used when handling exceptions
