Ok, not directed at you personally, but for future reference:

This is a BTX fault.  Kernel traps do not look like this.  If
you see this, you haven't even loaded the kernel yet and thus
your problem does not come from the kernel.  Since we got into
the loader, that means that the loader is b0rked.

As per this problem, it was due to a stupid error on my part
and is fixed in rev 1.19 of /sys/boot/i386/btx/btx.s.  Please
update your sources and recompile all of /sys/boot/i386.

Thank you.
