I have a dummy package that build-requires a bunch of linux-header
packages and the relevant -source package, and then runs:

 m-a -u . -i -t -f \
   -k "`echo /usr/src/linux-headers-[1-9]*.*.*-*-* | grep -v '*'`" \
   build PACKAGENAME

(and goes on to package the products in the dummy deb).

I just feed it to pbuilder and get the modules for all the kernels I
need.
