What would break if the new files were simply added to the existing 
kernel-dev
package ? I'm already putting System.map and others on targets in
different environments for dev/debug, so would adding enough to build
kernel modules on the target be a big problem ?

But I probably just don't understand *what* the existing -dev package
is used for, and my comment makes no sense :)

Outside of that, I also like linux-kernel-headers as the package name.
