Comment 17 for bug 585853

FTR I'm seeing this on maverick, with radeon.modeset=1 (and options radeon modeset=1) on a Thinkpad T60p, lspci says "ATI Technologies Inc M56GL [Mobility FireGL V5200]", with the fglrx drivers --purged (because they dropped support for this chipset a while back - with the useless proprietary drivers installed, X starts fine but all GL code (glxinfo, glxgears) dies with a near-immediate coredump.)

With the "start gdm, kill gdm, start xdm" workaround, I get working glxinfo and glxgears.

(I haven't tried turning off modeset with fglrx purged, yet.)
