The reason I want to try it is that the laptop appears to be running much hotter under KDE4 than it did under KDE3, so I want to test whether over-frequent updates is the reason or not. For instance, if I minimise this message then maximise it again, the fan will start. Obviously, if there was a problem with the temp mounting I would take it out again.
Does CentOS have a "laptop mode"? I'm only using this OS on servers, so I never tried laptop optimizations.
Ubuntu does, and it seems to help keep the machine more quiet and cool. I also mount local partitions "noatime", don't use 3D screensavers and don't enable the Compiz 3D desktop effects. That crap is a distraction anyway. Oh, and I also enable CPU frequency scaling. I'm using Gnome, but these optimisations shouldn't depend on the desktop environment. Maybe KDE enables some graphic effects of its own, I don't know.
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.
