So I have a possible "real" fix for this.  However, I do not have any hardware 
I can find that has a PCI-PCI bridge with the ISA-enable bit set.  I know it
compiles and boots fine on other systems.  Can you please try this and capture
the dmesg output?  It would also be good to capture devinfo -u output before 
and after.
