[CentOS] X using ATI ES1000: Failed to create write

I verified with my vendor that indeed we are using an ATI ES1000 Video 
Card, not an Nvidia as previously thought.

I am getting the following error -any suggestions?

(WW) RADEON(0): Failed to set up write-combining range

Is this a Horizontal/Vertical Sync Range issue?  I have Viewsonic E733 
monitor and am defining it as such in the config.

I am using system-config-display, which comes up just fine with X, but 
getting it to work after the config, it does not.

I'd just grab another card but this is a 2U server so dont have a low 
profile vga card on hand.
