Corrupted font rendering

Description of problem:
Text sometimes shows up with random dots or lines in it, especially in Firefox, on a Radeon Mobility 9000 chipset (Compaq Presario X1000 laptop). See attached screenshot.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. View pages in Firefox
Actual results:
Text has random dots or lines in it

Expected results:
Proper text rendering

Additional info:

-Setting Option "RenderAccel" "no" in xorg.conf works around the problem.

-I tested latest Xorg git a while ago and this problem did not seem to occur in that version. The Xorg driver ABI version has changed from the F10 Xorg version, though.

-I originally mentioned this under bug 444890 as it seemed to be a similar problem, however that one was marked as supposedly fixed. This particular problem is not fixed.

Xorg log file

This is my Xorg.0.log file. The problem occurs with no xorg.conf file (all default settings).

I think I see something similar on my wife's computer, except it happens without regards whether I use nomodeset or not (and not 100% reproducable, just happens sometimes).

Screenshot of the corruption is attachment 342608 [details]
/var/log/Xorg.0.log is attachment 342609 [details]
/var/log/dmesg is attachment 342610 [details]
/var/log/messages attachment 342611 [details]
/etc/X11/xorg.conf (quite minimal) is attachment 342613 [details]
