it seems like someone was confused about the meaning of the 'interrupts'
property when they wrote prom.c.  its basically the number of interrupts
supported by this pci device.  interpret_dbdma_props() also has the
same confusion, so the following would be a more complete patch to
prom.c.  note that it checks to see if a pci node has an interrupt
property before assigning one, otherwise devices on the far side of
a pci bridge (that shares interrupts) would be assigned interrupts
when they dont need them.

Today I tried your patch. Well, I breaks the hole interrupt stuff.
Now, even Mesh has trouble with interrupts (kernel crash), the
console=ttyS0 doesn't work so no output from the booting ...
