[ I had to also update libdrm from git to make everything compile. ]
The good news : X doesn't segfault anymore when running compiz... The
bad one : I now have another problem and I'm now getting an infinite
loop instead (100% cpu taken by Xorg). I'm getting the following
message ad nauseam in the logs :

tossed event which came in late
mieqEnequeue: out-of-order valuator event; dropping.
tossed event which came in late
mieqEnequeue: out-of-order valuator event; dropping.

Here's what I get if I attach a debugger :

(gdb) bt

I'm also attaching the full Xorg.log in case it could help...
