Not sure about this, now I've done it.  Running it here.

If you like it, I can do x86-64 as well.

lguest defines its own TSS struct because the "struct tss_struct"
contains linux-specific additions.  Andi asked me to split the struct
in processor.h.

Unfortunately it makes usage a little awkward.
