Dave, you have a good point about XP and SUSe commparions. But from
the Anandtech review, it says that it is faster in certain areas like
games, etc, but doesn't that also mean that OVERALL it should be
somewhat faster?

Is there anyway I can just overwrite the existing kernel? It doesn't
seem to work when you just reinstall SUSE 9.2
