From the land of the inexplicable, I rebooted, same kernel, and it 
worked! I should have clarified better, the can't map IRQ dmesg was 
from 2.0, so then I built a current kernel from todays sources with no 
patches applied and that's what the panic and now, non-panic is from. 
Since I should know better than not posting full dmesgs by now, here's 
the whole thing. IRQ 25 seems to be correct as slot 1 is 23 and slot 2 
is 24. It looks like it probes everything fine. The starfire nic's 
won't send packets though, tcpdump shows data coming in off the wire, 
and ifconfig -i shows packet counters incrementing in both directions. 
So nothing wrong with the pci code for me, keep up the good work! Sorry 
for the noise!
