The change in interrupts is due to it now using the MPIC for PCI
interrupts instead of the legacy PIC support in with the MPIC
in the default passthrough mode. Raven/Hawk boards got support starting at
2.2.8 but a couple lines of code got dropped somewhere.  My patch I posted
yesterday solves this problem...it wasn't setting the interrupt handler to
the openpic code as it should.  Thus, the first PCI device that tried to
init during boot hangs the system (SCSI).  I've tested this patch on MTX,
MVME2300SC, 2400. and 2700.
