In case it helps, here is the stack trace. By the way, I've also now 
tried setting:

ifconfig_mc0="inet 10.0.1.107 netmask 255.255.255.0"

but it still panics.

Here's the panic error, then the stack trace:

Configuring network interfaces: mc0.
Adding interface aliases:
Kernel Illegal Instruction trap.
trap type 2, code = 0x0, v = 0x0
kernel program counter = 0xc86de
kernel: Illegal instruction trap
pid = 50, pc = 000C86DE, ps = 2100, sfc = 1, dfc = 1
Registers:

<blah blah>
