I don't believe this is the right list for this type of question.  You
might get more help on ubuntu-users.

As for your question, I haven't done this in forever, but I recently
guided a friend in the right direction, so I'll try and point you the
same way.  There is a package called kernel-package.  This contains a
program named make-kpkg.  It will build debs from the kernel source in a
quick fashion.  You can use upstream kernel source or Ubuntu kernel
source.  I would go with Ubuntu's.  You can find it on  You will need the *.tar.gz, the *.dsc, and
possibly a diff.gz.  You should use dpkg-source on the dsc file to
extract everything.  The create your config and build your kernel with
make-kpkg.  You should then have a deb you can install.

Of course the above instructions are incomplete and fraught with
problems, so only do it if your willing to read the documentation.  If
you can live without hardware raid5, I would.  I have been very happy
with software raid5 under linux and never really had a problem with it.
 You may want to look in that direction.
