Fedora 13 + nvidia + kde

[slamp slamp]

I had a problem logging into KDE after an upgrade from Fedora 12. I
have akmod-nvidia installed. To fix the login issue I had to remove
/usr/lib/libGL.so.1 as I was seeing ksmserver: symbol lookup error:
/usr/lib/libGL.so.1 in my xessions log file.

anyone know a better fix? the nvidia driver provides its own
libGL.so.1. not sure how to get KDE to use that instead of the one
provided by mesa-libgl.
