Fglrx drivers are far to be fixed... :(
Firstly they're not usable now (using this way there are many problems
also if compiz basically works), then I don't think ATi is so interessed
to these things since it's more than an year now that AiGLX
specifications are out (really more the composite extension ones) and
now we started to see the first move...
However I'm not so intrested on what ATi offers in their proprietary
drivers, since I do really prefer using the free ones... My wish so is
that AMD whould release specs instead of binaries...

Of course... I think the same. I didn't know that code until Maniac
linked me it... It's really better from a code and implementation point
of view, and of course that is the code that should be merged, but from
my point of view it's hard to maintain since it changes really many
parts of the code... So that should be the choice, but only if merged
upstream!

Eh, that is what I thought, however without recompiling them all I got a
segmentation fault, that's why I said that maybe should be changed...
