Here's updated patch that actually works. I added it to xen-3.4.1-1.src.rpm
and verified the resulting rpms are able to boot lzma compressed kernels.
It's still not final patch, since the stubdom/pvgrub bzip2/lzma support is
not yet included in this patch (until the proper method for Makefile hacks
is determined upstream).
