No, I don't get that (with the 32bit x86 Xorg at least). Some games 
(ut2k3 for instance) segfault when run with indirect rendering, but this 
is nothing new that never worked. The mesa demos seem to work for me, 
with the exception of that #4087 (it crashes the X server VERY fast, in 
about 1 out of 10 cases I don't even have to move the 3d window around, 
just starting a demo is enough to instantly segfault the server).
