Comment 7 for bug 44112

Gentoo bugs asked me to move this upstream :
http://bugs.gentoo.org/show_bug.cgi?id=140471

What happens is this.DRM direct rendering is showing
enabeled for the voodoo3 AGP card and has the expected
1360 fps after the update to modular X v 7.0 ( stable )
The other voodoo3 pci ( i got dual head ) is not accelerated
and has also the expected 250 fps or so with glxgears.
But any application using GL crashes with "Segmentation
fault". ( on the accelerated card, they work but real slow
on the pci card )
I have managed to produce a backtrace for TuxRacer
