It's already in the mainline kernel, e.g.:
commit 30d65dbfe3add7f010a075991dc0bfeaebb7d9e1
Author: Alain Knaff <al...@knaff.lu>
Date: Sun Jan 4 22:46:17 2009 +0100
bzip2/lzma: config and initramfs support for bzip2/lzma decompression
Impact: New code for initramfs decompression, new features
This is the second part of the bzip2/lzma patch
The bzip patch is based on an idea by Christian Ludwig, includes support for
compressing the kernel with bzip2 or lzma rather than gzip. Both
compressors give smaller sizes than gzip. Lzma's decompresses faster
than bzip2.
It also supports ramdisks and initramfs' compressed using these two
compressors.
The functionality has been successfully used for a couple of years by
the udpcast project
This version applies to "tip" kernel 2.6.28
This part contains:
- support for new compressions (bzip2 and lzma) in initramfs and
old-style ramdisk
- config dialog for kernel compression (but new kernel compressions
not yet supported)

For older kernel versions, you can backport it by git cherry-picking the
commits you need.
