Fedora X86/64bit :: FC14 Wont Get Past Initial Black Screens?

I have a PC installed with FC 14:AMD 9500 Quad Core4GB RAM2x ATI X1950I've been using FC14 for a few weeks after updating from FC13.The graphics driver was a default one, it worked but it would only recognise one of my screen cards and I wanted to install the ATI Catalyst software so I began the process of installing the proper drivers.I followed the howto at: http://forums.fedoraforum.org/showthread.php?t=155503 Once I'd finished the driver seemed to be sort of working but everything was going really slow. If I moved a window it'd take a while to redraw in the new position, menus took ages to pop up, and so on.

I tried running aticonfig and got an error message (unfortunately the only record of it is on the machine I can't access properly). I put the message into a search engine and found a bug stating the same message where people had the same problem with Nvidia and intel cards too.The problem was something to do with python and how it started up the drivers (sorry I can't remember the message). The bug had an rpm attached that was a patch to fix this problem (I'm blabbing on in case any of this jogs the memory of someone that had this problem or worked on it).I installed the patch and rebooted and now Fedora gets as far as the black screen where a progress bar fills in white at the bottom of the screen but it stops there. Once the bar is completely white it sits there and gets on further no matter how long I wait.Does anyone know how I can recover this system? Is there a way of getting the system to recreate xorg.conf before this stage and load using the default driver again? The point it's hanging at is the point where it would normally bring up the graphical progress bar then the login screen.
