Hi Mathieu, I had the same problem with Firefox since I upgraded to CentOS 5.5. I noticed very slow (almost unusable) Oracle Enterprise Manager 10g (Database Control, Grid Control and Application Server Control) and MS SharePoint pages, high X.org cpu usage and noisy fans activity. I couldn't find anything about this on the web. Firefox downgrade didn't help, but finaly I realized that I upgraded nvidia driver too - problem disapeared right after downgrade to nvidia driver NVIDIA-Linux-x86_64-180.22-pkg2.run. There are alse other versions between, but this one is the last one IMHO where PowerMizer works as expected (at least on my laptop). My configuration is CentOS 5.5 x86_64 @ Dell Latitude D830, Nvidia Quadro NVS 140M.
