It seems likely that Bochs emulation isn't sufficient to cope with the tricks 
Xen uses...  You might want to look at switches to get different CPU 
emulations from Bochs.  You might also want to look at a debug build of Xen 
(cd xen; make clean && make debug=y; cp xen.gz /boot/).  Report a bug to the 
Bochs people if it really won't work.  Finally, if you're completely stuck 
you might like to try QEmu - it should boot the Bochs image happily.

Cheers,
Mark
