Is this problem independent of menus?

The Linux code should not have a20 problems.  It has been a little
while since I tested mkelf but it was working at the time I made the
patch to generate the checksums.

And note some machines have a20 set permanently on.  So while we may
confuse some machine's BIOS's by not restoring a20 that should be all
we confuse.
