Mmm... interesting. Note there's also Xorg there, taking too much of your
CPU cycles. I've seen this before, Google will confirm:

But if you say you experience the same problem with another applications,
this points to a component that is shared between them, and I can only
think in Xorg and the VGA drivers. There's a additional "but" here and is
that as you are using Lenny, I can guess that none of these two could have
changed recently so the mistery still remains unless you installed "something"
recently :-)

Well, yes, the Firefox start page shouldn't be problematic _unless_ you are
using the new feature that displays the latest visited sites in thumbnails ;-)

GNOME system monitor can become an intensive task, I mean, is not a good tool
to use to compare with, but you can try to reproduce the CPU pikes launching
different applications (e.g., OOo writer, gedit, any Qt based app that you may
have installed, a java tool...).
