Public bug reported:
When run with a bootstrap loader that uses int 0x10 with 0x1301 in %ax,
incorrect video modes are output to the serial port. I believe the VGA
image will be correct. This might also affect the returned values for
some interrupts.
This is caused because the set_cursor_position routine fails to save and
restore %bx.
I'm working on a fix for this.
