Let's give the OP some truth because the inability to upgrade kernel
modules for older kernels imply his statement:

Given that updates of kernel modules for older kernels are not
possible, if the kernel module depends on userland (like ipw3495
daemon or a firmware) which get's updated, too (there is s strict
matching between ipw2x00 versions and what firmware is allowed), then
the old userland package get's updated disabling the kernel module. Or
if the kernel module package had a strict depdendency on the userland
package it will get removed package-wise, too.

These are two existing examples of how the kmod scheme will indeed
nuke you old kernel's wireless support, if the kmdls would had been
transformed to kmods. It's not difficult to move the argument to a
storage device driver like 3w-9xxx or qla, both of which exist in
kmdl form.

kmods are like walking on very thin ice.
