Having this problem too with a mesa built from a 2 days old git snapshot.
The problem occurs when trying to launch a WebGL demo
(http://www.chromeexperiments.com/detail/glass-shader/) using Firefox 10.0
(x86_64).
On the shell the following message appears:

radeon: Cannot get a relocation in radeon_drm_cs_write_reloc.

and then Firefox crashes.
Reading the previous comments I looked at dmesg too and the following happens:
1) When using a 3.1.0 kernel, some lines similar to those already mentioned in
the above comments appear;
2) When using a 3.2.5 kernel, nothing appears in dmesg anymore after Firefox
crashing.
I tried using the 3.2.5 kernel because I thought that some changes undergone in
libdrm would only be available with a newer kernel.
My system specs follow:
CPU: AMD Athlon 64 FX-55
GPU: ATI Technologies Inc R420 JP [Radeon X800XT]
OS: Slackware64 13.37
Mesa git snapshot taken on February, the 7th
libdrm-2.4.31

If more information is needed, please tell me.
