Just realized thats where my smbus IO base is. I'll try moving things
around a bit, I don't even need smbus at the moment.

Heh, I went ahead and dumped my mptable, even though this is a single
processor system. The mptable is for a supermicro P4DPE (with intel
e7500 chipset). Just one more reason factory bios's suck.

I'm having a bit of trouble with your acpi tables, they just don't seem
to work right on my board, so I'm working on patching up the factory
tables. Just out of curiosity, do you now have a device 10.5, which
linux detects as a network card? This is a USB direct device
comminucation device, but Linux seems to think it's a NIC, and I think
that trying to initialize it is what's hanging my system at the moment,
but I can't be sure.
