 Nice! Does DRI work?
Not on my side. Plus i can't visually jump over 8bit depth, although Xorg
 states 24bit in it's log.
 As for DRI, i'm experiencing
 "ring test failed (scratch(0x15E4)=0xCAFEDEAD)" with a firegl x3.
 FWIW, I'm seeing the same failure on my FireGL X1:

Have you tried agpmode=-1 to force PCI mode. It seems like this was a problem at one time on ubuntu:
