Hi Sam,

I've got a v5200 (slightly older but mostly the same) chip in my T60p,
and here's what I've got in the "Device" section of my xorg.conf:

Section "Device"
        Identifier  "FireGL5200"
        Driver      "radeonhd"
        Option      "monitor-DVI-D_1"  "DoubleSightDVI"
        Option      "monitor-PANEL" "ThinkpadLCD"
        Option      "RROutputOrder"           "DVI-D_1"
        Option "AccelMethod" "shadowfb"
EndSection

The last bit is what it took to get my shadowfb rolling, I've got 

#        Option    "ShadowFB" "on"

in there but commented out so it must not have worked.

Anyway, things are quite nice in 2D with ShadowFB, and I'm being patient
for 3D acceleration for now (I reboot to windows to play games anyhow :)

    Alec
