I can now see why you didn't want to do that.. :) I managed to get the libs to 
compile, but now I'm having other problems..

"make stubdom" gets to the point where it compiles ioemu-stubdom, but it fails 
to link because xen-unstable.hg/stubdom/mini-os-x86_32-ioemu/mini-os.o has 
undefined references in xc_try_bzip2_decode and xc_try_lzma_decode functions.. 

I guess only pvgrub would need to have this stuff in? I've been trying to
figure out how the makefile magic works, but haven't really understood it yet.

Any tips how to make ioemu-stubdom compile/link without including bzip2/lzma 
stuff into it?
