It works on Intel because there we emulate the rombios, and our emulator
does not bother with segment limit checks in real mode. This is actually
more lenient than real hardware, hence an AMD CPU (which is directly
executing the rombios code) will fault on the access because it is at a
segment offset greater than 64kB.

Your patch is good. Please re-submit with a fixed changeset comment and a
signed-off-by line. I'll then check it in.

 Thanks,
 Keir
