Your firmware is apparently attempting a "movl %cr0,%eax" in V86
mode.  BTX, which hosts boot2 and boot/loader, doesn't currently
provide emulation of this (privileged) instruction.

It will be easy enough to make provision for this, but it may be
safest to check out what exactly is happening here; so if you want
to dd(1) the 16K of physical memory starting at 0xcc000 and send
it to me, I'll take a look.

Anyway, there should be a fix to try in a day or two.
