How to restore shipping kernel and modules

OK I screwed up in an attempt to "optimize" a self-compiled kernel using Suse 8.2 pro. All works fine except hotplug fails to start. At this point I just don't have the time to learn how to diagnose and fix this. Sadly, before the recompilation I lacked the brains to backup the shipping 2.2.40-4GB modules. I have the original kernel. How do I restore the shipping modules into /lib/modules? TIA, Bernd
