Hm, did you load this via the Ethernet, or copy it into flash and boot
it from there?

Hm. Ok, this is different from my IQ80310 setup:
obio0 at mainbus0: board rev. F, CPLD rev. D, backplane present
iopxs0 at mainbus0: i80312 Companion I/O, acting as PCI host
Now, this "is_host" variable is consulted when the i80312 is configured.
In particular, if is_host is false, then the assumption is that we're
plugged into a PCI host that will configure some i80312 paramters as part
of its own PCI bus configuration. This could be part of the problem.

Which Intel Gig-E is this? My i82544GC parts have a product ID of 0x100c.

Hm. This is strange. Is the physical address space laid out on
your board differently from a stock IQ80310? Can you please use
gdb to determine what source file/line that PC maps to? (It maps
to uvm_swap.c:933 in my source tree, but my tree is almost certainly
different from yours, and so it's not very meaningful.)
If you don't have a cross-gdb, you can get one by doing:
MKCROSSGDB=yes ./build.sh -t -m evbarm ...
(...it's not built by default...)
