Are you sure the second machine is fully updated, and running the latest 
kernel? Try to do a "yum update" again, and reboot the machine, there were 
some recent (couple of days ago?) updates to some xorg packages...

I had the same issue on two machines with intel graphics hardware. The stock 
F16 install came with the kernel and xorg packages which didn't work on either 
of my two machines. They *appeared* to work, the "glxinfo | grep direct" 
reported that direct rendering was enabled, the glxgears did work as expected 
--- but trying to enable the KDE4 dektop effects would fail miserably, just as 
you described.

However, one of the recent updates involved a new kernel and some fresh xorg 
packages. After that everything became functional, and works beautifully. ;-)

HTH, :-)
