Unhappy Radeon 9600 Hardware Acceleration = Lose

I've got a radeon 9600 pro (256MB) card running at the moment on the latest fglrx drivers from livna and I've been having a constant problem with the hardware acceleration for said graphics card (through several kernal and driver updates). For some reason whenever I enable hardware acceleration for the card, it screws up the X server. I have managed the problem by commenting out "Load Dri" in my xorg.conf which disables hardware acceleration but I'd like to get the card running properly so I can do stuff without getting video lag...

What it does to the X server:
I occasionally get the urge to try and fix the hardware acceleration on the card and in a fit of enthusiasm, I uncomment the "Load Dri" line in xorg.conf and reboot. The boot process goes along nicely, and the fedora splash screen progress information thing comes up and loads (the one where you can click "details" and watch everything load) and after this, where the login/greet screen should come up...nothing comes up. I get a black screen which I assume is blank and indicates some big screw up. I've tried commenting out HSynch and VRefresh and setting DPMS to true (I picked up somewhere that this would allow the screen to resize by itself or something...) but that didn't work.

What I don't understand is that my friends who has the exact same card (we have similar systems overall too) got his hardware acceleration working without a hitch first time. It's just something to do with me...We have different monitors (I have a NEC CRT and he has an Optima LCD) but I tried booting with hardware acceleration on a borrowed LCD monitor and had no promising results.
