I could use some help here!

I just installed RED HAT 6.1 on my Gateway machine.  It iss on a seperate 
spindal.

The system installed properly - however  Linux complains about my video card 
and won't start XFree86 server..  Says it has problems accessing the memory 
on the card.

The card is an 'ATI Rage 128 GL AGP  (English)'.

The question is:  Has anyone used this card with linux?  Any suggestions on 
getting X to work.
