it's a very long time I'm wrestling with the very same issue with my mobility
x1400. Today I found a workaround to did problem. I'm in kernel 3.2 of LMDE. 

To solve this problem I forced my GPU into the maximum compatibility 3D
acceleration mode with this simple xorg.conf

Section "Device"
    Identifier            "Radeon"
    Driver                "radeon"

    Option "EXAPixmaps"        "off"
    Option "AccelDFS"        "off"
    Option "MigrationHeuristic"    "greedy"
EndSection
