I think this whole thing should be a compile-time option. It assumes that BIOSes
actually do what they are supposed to. I know from experience that they don't.
They're usually buggy to one extent or another and there's no guarantee that the
writer understood the specs.

Also, please don't perpetuate the myth that as86 can't do 16-bit relative jumps.
The code
lea cx, end_memdetect ! gas can't do 16-bit offset jumps. very annoying.
jmp cx
can be replaced by
br end_memdetect
