Regarding Bzip2, some testing showed that the decompressor needs at least 3.5Mb
of memory available for malloc(), which is not available on ARM as head.S
allocates only 64kb, so I'm sure what to do about it. At this stage, I think
the most sensible thing to do is forgetting about using bzip2 on ARM.

The LZMA patch relies on patch 2/4 of the LZO patchset, which I resubmitted
today: http://lkml.org/lkml/2009/11/11/129. I'll likely submit the LZMA patch
once I get Russell's approval on the ARM part of the LZO patchset. In the
meantime, you can get it here: http://alioth.debian.org/~lutin-guest/patches/
