I tried the latest CVS version and found that X and startx seemed to die as processes after a short time running on the 815 video card . Gnome kept using whatever residual elements were on screen 7. Anyway, I submitted the below bug against the i810 driver.
https://freedesktop.org/bugzilla/show_bug.cgi?id=1232
As a note: I am compiling the src rpm w/ the below commands to see if it fares better. .. rpmbuild --rebuild --target i686 xorg-x11-6.7.99.903-1.src.rpm
At least it is alive again. After compiling and installing the i686 rpms, the results will be added to the bug report.
Just in case other users have similar troubles w/ the latest driver.
