Ati (fireGL) drivers

Hi guys

I own a ATI hd 4850 512MB graphics card manufacture by XpertVision. Now I've read that ATI usually have some display problems with MAYA which I'm also facing. One problem is that in the paint effects the brush trails keeps on forming and the view port never refreshes. After sometime the whole view port becomes red. I've read somewhere that ATI workstation card solves that problem (fireGL). Now my question is that is there anyway that I can install the FireGL drivers on my current card which ofcourse is not a workstation card coz I read somewhere that it can solve the problem. If yes, than please guide me that which fireGl driver to install to get rid of this problem. Currently I'm using the latest drivers for my card and catalyst 8.12. Please help me!!
