1)I cannot understand why the WEAK entries are required after the
bad_subarch label :/ Any hints?
2)I think that xen doesn't use any more the hardware subarch boot
parameter, and uses a 'different' path/boot sequence, hence the
xen_entry in head_32.S is not needed any more. Am I missing something?
Thanks! :)

Yep, Xen never actually used it.

Does lguest use it? It looked like a neat idea - what happened?

yeap, afaik, lguest uses the subarch field to jump to its own 'entry
point'...
