This option is not selected in my configuration but is is slow since
the upgrade to X.org 7.2 with firefox. I have alse rebuild firefox after
all was rebuild.  It is only with Firefox.

I have the following modules loaded.
    Load        "dbe"   # Double buffer extension
    Load        "extmod"
    Load        "glx"
The card is a Radeon 9250 AGP.
What can I try?
