Comment 3 for bug 507148

Users with this card are reporting that their systems either do not boot up (systems with 16MB video ram) or lose compiz shortly after booting (systems with 32MB). dmesg indicates TTM has run out of memory:

[ 213.812640] [TTM] Failed moving buffer. Proposed placement 0x00060004
[ 213.812650] [TTM] Out of aperture space or DRM memory quota.
[ 213.812660] [drm:radeon_object_create] *ERROR* Failed to allocate TTM object (5914624, 0x00060004, 0)
[ 213.812667] [drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM object (5914624, 4, 4096)

[Original Report]
The livecd will not boot to the desktop. Selecting "install" from the boot menu will install lucid, but after typing in password at gdm screen, desktop session will not start.
This is with the 20100113 lucid i386 livecd on a Thinkpad T30.
