Thanks for your reply.

These dependencies actually come from kernel.bbclass, where it sets
the RDEPENDS of each kernel-module-*.

It seems I need to modify kernel.bbclass to get what I want, so I
asked here first.

I use these 2 packages as example because this situation actually
should not happen.  I installed a new set of kernel  (3:xxx) but some
of the old modules are still there. (2:xxx)  These two packages are
unrelated to each other so one cannot relace the other.
