Yep. It's possible that at least the distro kernels change to using
better compression methods (bzip2/lzma) in the future, so then pv-grub
should support them aswell.

I've been working on adding bzip2/lzma support to pv-grub, but haven't
had time recently to finish the project.

If you'd like to work on it, let me know, and I can point you to the
latest (not yet working) patches.
