I am trying to install the FC5 fglrx rpms from Livna, it all install fine but when I restart X it gives me an error

dlopen: /usr/lib/xorg/modules/drivers/fglrx_drv.so: cannot restore segment prot
after reloc: Permission denied
(EE) Failed to load /usr/lib/xorg/modules/drivers/fglrx_drv.so
(EE) Failed to load module "fglrx" (loader failed, 7)
(EE) No drivers available.

I can use the include tool to disable the drivers, and get back into X fine, but whenever I enable them, X will not start back up.

EDIT: Ok, I have disabled SELinux in the meantime, which has resolved that error, and the driver is loaded, listed in lsmod, and X is up and running. But I still only get 200+ FPS on glxgears. From what I understand it should be in the 10,000's. No errors come up when glxgears is run, no errors I can see in messages or dmesg. Does anyone have any ideas?

PS. Direct Rendering is shown as "No" in glxinfo
