Slow graphics after last kernel update (I think)

Hello fedora list. 
I updated my IBM Thinkpad R51 running fedora 12 a couple of days ago. 
Now lots of applications that used to work runs very slow and CPU throttle
seems to be at max almost all the time.
Gnome-system-monitor takes up to 5 minutes to start, it used to start in
seconds. 
Supertux runs at about 3 frames/second, used to run a lot faster. 
Scrolling content in firefox is very slow and CPU throttle hits max
instantly and stays there for a long time. 
Flash from youtube in firefox runs at 2 frames/second, used to run at
about 20 frames/second. 

The compiz animation stuff still works at same speed. 

The automatic bug reporting tool gave me this the other day while the
system was logged in but no apps were running on the desktop.

Booting on the previous 2.6.32.14-127.fc12.i686 kernel seems to solve all
these problems. 
Does anyone knew what's going on here ?
