Try using the unsupported option:

	Option "ForcePCIMode"

That option is useful for 2 things:

1) It allows PCI Radeon cards to enable DRI experimentally, and 
   may work perfectly or may crash horribly.  Very experimental 
   and unsupported, but bug reports are appreciated nonetheless 
   so that I can investigate them if I ever have time, just don't 
   expect any official high speed fixes.  ;o)

2) It allows AGP Radeon cards to be treated as if they were a PCI 
   Radeon card and use pcigart for DRI.  Same caveats as #1 above 
   apply here. 


Your other option is to rebuild the XFree86 rpm from src.rpm with 
XFree86-4.3.0-Mesa-SSE-fixes-from-MesaCVS.patch patch disabled.  
That might or might not allow you to use the 2.6.x kernels.
