Xorg uses incorrect renderer with fglrx driver on R420


Hi, I've installed the the fglrx driver package from the livna repo in FC6. The problem is that fglrx is still using Mesa Indirect rendering and not the ATI rendering that I would expect it to have used:
Code:
[cory@localhost ~]$ su -c glxinfo | grep direct
Password: 
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect
When I ran aticonfig, it did something odd to my xorg.conf and sections are doubled. Is it ok to comment/remove the sections that were not generated by aticonfig? Does it even matter? :
Code:
# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "single head configuration"
	Screen      0  "aticonfig-Screen[0]" 0 0
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

EndSection

Section "Monitor"

EndSection

Section "Extensions"
        Option  "Composite" "Disable"
EndSection

Section "ServerFlags"
        Option  "AIGLX" "off"
EndSection
Anyway, I want to get rendering working correctly because the entire reason I switched to the fglrx driver was that 3d rendering with the "radeon" driver produced horribly poor perfomance. Thanks in advance for any help.
