Xorg+KDE freezes if the "RenderAccel" is "true"

[Andrew Muhametshin]

If option "RenderAccel" is "true" (in xorg.conf), at start of the some 
KDE-programs (konqueror,khelpceter,kcontrol, but not gtk/gnome 
programs), the KDE freezes, and does not react to the keyboard and mouse.
This problem does not depend if compile driver with option(AGP GART or 
nvidia AGP).
Аlso does not depend on if all options in section "Extensions(in 
xorg.conf)" (Composite, RENDER, etc.) are disable or enable.
Only if "RenderAccel" is "true".

$ dmesg | grep -i nv

I start the Xorg and KDE.
After the Xorg+KDE has frozen.
