[PATCH] x86emu: improve single-step debugging

[Kees Cook]

This is a seriously old thread, but it's still been hanging around in my
inbox, unresolved...

What's needed to apply my patch to both Xorg and libx86? Neither code bases
have changed in several years, and Xorg is still using its internal copy
instead of the Matthew's external libx86.

Thanks!
