[Xorg] Strange crashes caused by radeon pagesize cleanup/update?

[Tarmo Tänav]

Well, found another thing, by only using 6-30

When I accidentially defined my like this:

    SubSection "Display"
        Depth       24
        Modes       "1280x1024" "1280x960" "1152x864" "1024x768"
"800x600"
        Modes       "1280x960" "1152x864" "1024x768" "800x600"
        Virtual     0 0
    EndSubSection

it caused the same problem as with the other versions.
By removing either one of the "Modes" lines the problem didn't happen
anymore. What really happens if there are two "Modes" lines?

And I also found out that by using disabling Render acceleration like
this:    Option      "RenderAccel"       "False"
the crashes ceased to happen.

Please tell me if there's anything else I should test or if I'm way
wrong and it is my own machine probably causing this problem.
