More info.
I created a new user and logged in with that choosing Gnome/Openbox in GDM3
login screen as window manager. Did not change any settings or do much, default
session created by system. Same thing, CPU full tilt and heating up.
I had previously checked using LXDE as desktop environment worked OK, no extra
load and no heat problems. So something in Gnome seems the probable culprit.
Followed advice by Cyril Brulebois. Looked at the top output, and killed
prosesses taking most CPU. One version of top listing in original bug report. It
changes somewhat, here is one more:

Left Xorg alone, it takes most CPU but I guessed killing it kills X Window
session. Used kill -TERM <PID> to remove prosesses.
dbus-deamon: killing it had no effect on CPU load.
gnome-session: killing it killed the session, had to log in again
gnome-settings: a new prosess started, no effect on CPU load
gnome-panel: a new process started, no effect on CPU load
gnome-power-man: no effect on CPU load
nautilus: a new process started, no effect on CPU load
metacity: CPU load disappeared. Window borders changed but otherwise Gnome
works as before.
Tried this metacity killing four times, every time same results. So it seems
metacity is started automatically by the system, but now it causes problems.
This did not happen before saturday. I still think this problem originally
appeared after upgrading x11-xserver-utils to version 7.5+3_i386. On the other
hand, it seems strange that downgrading to version 7.5+2 did not help. I was
originally going to report bug against x11-xserver-utils, but hesitated when
donwgradind the package did not help any. Now it seems metacity might be the
correct package to get bug report.
This Debian is originally Lenny, updated to Squeeze two weeks ago. Perhaps there
is something here that is not present in freshly installed Squeeze, and that
causes metacity or Gnome to throw hissy fits? I would expect lots of bug reports
if all Gnome users got this problem after upgrading x11-xserver-utils.
