L2000, PDC 40.48, Fully populated all add-on slots with misc PCI cards.
The fact that PCI graphics cards were added complicates
things since they consume lots of MMIO address space - more
than we normally have for a distributed range per Elroy.
"Failed to allocate resource" messages are not surprising.
Data page fault at the end is due to some bug of my own in
the interrupt handling code. John Marvin needs the l2k for
large mem work and will remove the extra PCI cards for now.

ldw 34(r19) is trying to read isi->isi_region->data.irqbase.
isi->isi_region seems to be a NULL ptr. *sigh*.
Enabling DEBUG_IOSAPIC (and thus ASSERT) changes the location
where the code data page faults.

So perhaps I'm wrong about the culprit being isi->isi_region being NULL
since I would have expected an ASSERT to catch that.
