No 3D after dist-upgrade to X.org 7.0

Upgrading from Xorg 6.9 to 7.0 was tricky. I could get this done with Kano's scripts but still 3D don't work. My X.org version is 7.0.19.

I had same kind of troubles after upgrading from 6.8.2 to 6.9 but it was fixed automatically after some minor updates. There has come tree or four minor updates to 7.0 version of X but still no 3D :(

My graphics card is Matrox G450 but same trouble is with all computers I have tried my remasterings (different cards where previous version of X worked but that new not).

What can cause this?
