Fedora Video Card Problem

[Matt Cook <Aceofspades12491@xxxxxxx>]

Ok so I recently installed FC6 and it seems that My ATI card isn't 
compatible. When I boot after the install, it wants to black out the 
screen and act like the monitor isn't receiving a signal. Now I did take 
it out and use the stock card on the Mobo (Intel Grpahics Media 
Accelerator) and it worked fine. The thing is, it's a pretty pricey 
card, and i dual boot with winxp, which can use the card. Is there a 
driver that i can dowload, or some configuration i can change so that i 
don't have to take out the card every time i want to use Fedora?
