There are people who got PCI radeons working. The driver could just
treat your AGP radeon like a PCI one. Try adding this line to the Device
section of XF86Config-4.

   Option       "ForcePCIMode" "true"

I'm not 100% sure, but I thought the DRI extension was hardware
independent. So maybe you're just missing a few lines in XF86Config-4.
The Module section should include these two lines:

   Load "dri"
   Load "glx"

It would be helpful to see your full XF86Config-4 and
/var/log/XFree86.0.log to know exactly what's going wrong.
