There is a 'debian way' of making packages for kernel modules not in the 
kernel tree, producing a package that depends on the kernel package you make. 
I used it to keep the fuse module up to date a while ago. I'll see if I can 
find my notes on the details if you like, but make-kpkg rings a bell.
