GLX works... But glxgears doesn't...

[Hamish]

I'm running an X550 (256MB Saphire) on a 2.6.17.1 kernel, AMD x2 4200+, socket 
939 and 3GB of ram. I have the ati drivers from git. (About a week old). 
Google earth runs fine, a bit stodgy sometimes, glxinfo reports I have dri 
etc, but glxgears exits with a DRM error, and dmesg shows

hamish at damned ~ $ glxgears
drmRadeonCmdBuffer: -22 (exiting)
hamish at damned ~ $ dmesg|tail
[drm] writeback test succeeded in 1 usecs
[drm] Setting GART location based on new memory map
[drm] Loading R300 Microcode
[drm] writeback test succeeded in 1 usecs
[drm:r300_emit_3d_load_vbpntr] *ERROR* Offset failed range check (k=0 i=2) 
while processing 3D_LOAD_VBPNTR packet.
[drm:r300_emit_packet3] *ERROR* r300_emit_raw_packet3 failed
[drm:r300_do_cp_cmdbuf] *ERROR* r300_emit_packet3 failed
[drm:r300_emit_3d_load_vbpntr] *ERROR* Offset failed range check (k=0 i=2)

[drm:r300_emit_packet3] *ERROR* r300_emit_raw_packet3 failed
[drm:r300_do_cp_cmdbuf] *ERROR* r300_emit_packet3 failed

Setting LIBGL_DEBUG doesn't give a great deal more (Except missing drirc)

hamish at damned ~ $  export LIBGL_DEBUG=verbose 
hamish at damned ~ $ glxgears
libGL: XF86DRIGetClientDriverName: 4.1.0 r300 (screen 0)
libGL: OpenDriver: trying /usr/lib64/dri/tls/r300_dri.so

drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
libGL error:

libGL error:

drmRadeonCmdBuffer: -22 (exiting)
hamish at damned ~ $ 


Any quick ideas (For finding more info about what's happening)? Failing that, 
it's code reading time for me when I get home.

TIA
