It happens so often, that I finally decided to "fight back". I backup
/etc/modprobe and any /etc/sysconfig/network-scripts/ifcfg-eth(x), and
restore those files after upgrade. Seems ro work fine (fingers crossed).

Not upgrading kernel is OK only if the system is really firewalled and the
clever users can not access it, in other words, you really should apply
security updates.
