gdb log of Xorg-1.9.0.901 + xf86-video-ati-6.13.2 + Mesa-7.9 under Electric
Fence

I don't know how to turn off 3D effects in gnome desktop, but running the X
server under electric fence gets a memory fault in free() in 3D initialization
shortly after I log into the gnome desktop via gdm.  This is with ElectricFence
configured to allow zero length mallocs.  I have attached a gdb excerpt.

The attached gdb excerpt is from Xorg-1.9.901 + Mesa-7.9, but it also happens
under Xorg-1.9.0 + Mesa-7.8.1.

Also thanks for the note about the 4K texture size limit.
