Ahh.. now this panic I understand.  Its angry because I hardcoded the extent
for iomem for the 7044.  We are *definately* going to need per-model
information to do the io extents.

Here is the procedure to find out the proper io extent:

disable PCI_NETBSD_CONFIGURE and enable PCI_CONF_DUMP. Let the machine boot,
and for any device that has a sane set of BARs, record where they live.  That
should give you an idea of what the correct io range is.  You can test by then
re-enabling PCI_NETBSD_CONFIGURE, and leaving PCI_CONF_DUMP in.

Yeah..  probably just need to add that compatible id to the code in
powerpc/pci_machdep_ofw that looks for it.
