Could this possibly fix the problem I'm seeing with the screen being
garbage after a logout from KDE 3.x (using kdm)?  Everything works
fine after logging in, but when you log out, the screen is left with
garbage/lots of vertical striping.  This only happened after upgrading
my system (and all ports) to Xorg 7.4, worked just fine before that.
