The laptop doesn't run CentOS - my server does, but the laptop has Mandriva.
The local partitions are mounted 'noaatime', and, like you, I don't enable an
3D stuff. Desktop effects are not enabled, and CPU frequency scaling is
enabled.
I've been told that KDE 4.1 is better on this score, so maybe it's a bit like
when Fedora take the debugging code out as they get close to release.
