I built qemu with and without the patch with the emulator x86emu.
For me it takes 200 bytes in stage2/segment1 and 11 bytes in
Since it implements a few new opcodes, that's not surprising. I suppose we
could make those opcodes dependent on using the new emulator, but it doesn't
seem worth it.
With biosemu enabled, it takes just over 3K more in segment 1 and 31 bytes
in segment 2. As advertised: larger, but not huge.
