I have 2.6.4 working with the realtime-0.0.4 module. I didn't have time
to investigate getting it to fit into a debian kernel package, so I just
made it separately again and continue to insmod it from
/etc/init.d/bootmisc.sh.
I did take a quick look at the make-kpkg man page. The --added-modules
foo option might be of interest. I think it's meant to build modules
from source directories outside the kernel tree and perhaps include them
in the kernel deb package(?). But, I didn't have chance to play with it.
