Is that something we really want?  We never made any efforts at maintaining
ABI between kernel and modules, or in allowing this kind of combinations.  If
we go this path, it can mean more work later (e.g. support for building kernel
and modules with different versions of GCC, etc).

Could you give an example of a situation in which this would be useful?
