Hi, Kristian and the rest of the DRI world! ;)
Testing your most recent DRI2 work on my 945GM I ran into trouble
starting compiz.
Digging a little bit deeper I recognized, that glXGetFBConfigs seems not
to return any FBConfig at all.
But glxinfo lists a whole lot of them:

Another problem I see is the following:
~/software/mesa/progs/xdemos> ./glxgears
calling DRI2CreateDrawable, XID 0x4200002, GLX ID 0x4200002
success, head 0x9c8, handle 0x20
5828 frames in 5.0 seconds = 1165.460 FPS
DRM_I915_EXECBUFFER: -16
glxgears: intel_context.c:1010: UNLOCK_HARDWARE: Assertion
`intel->batch->cliprect_mode != REFERENCES_CLIPRECTS' failed.
Aborted
I admire the beautiful screenshot Kristian shows in his blog, but at the
moment cannot reach such positive results. :(
Greetings, Johannes
