although config wouldn't allow the:
options PCI_ALLOW_UNSUPPORTED_IO_RANGE

I put it in the COPTS and it compiled alright, but now its having 
problems mapping irqs

pcib2: routed slot 15 INTA to irq 255
pccbb: Unable to map IRQ...
panic: resouce_list_release:can't find resource
Debugger("panic")
...

Is this also an issue with pci_pci assigning resouces properly?  Also 
where might I find information on pci<->cardbus behavior if I do find 
time to tinker with the code?

thanks
