Need help finding an ATI update!!!

OK. so i found out that my compaq with an ATI mobility 9100/9000 IGP graphics card is not supported by the ATI website. It also can't accept the Catalyst update. So ive been forced to try and find an update on the HP webste. Can anyone help me find a update for my card? If not im going to go burn $200 on a good nVidia card.

Have you checked out the driver page here? I found one that seems like it should work, it lists both the 9000 and 9100 mobility cards.
