Are you sure Linux uses bzip2?  According to the docs
(linux/Documentation/kbuild/commands.txt):

Note: the difference between 'zImage' files and 'bzImage' files is that
'bzImage' uses a different layout and a different loading algorithm,
and thus has a larger capacity.  Both files use gzip compression.
The 'bz' in 'bzImage' stands for 'big zImage', not for 'bzip'!
