The 2.6.9-22.EL kernel is RHEL4 Update 2. You may
want to contact someone from the LSI MegaRAID group,
or Red Hat since this is a binary only deliverable. You
should be able to find a MegaRAID contact in the MAINTAINERS file
in the top directory of the kernel source tree.

I work on mpt fusion drivers, which is a seperate division within LSI.
