(Radeon RV200 QW PCI) difficulty enabling DRI

[Andy Goth]

I'm not having much luck setting up DRI.  I'm sure I had it working on
this system once before (using Ubuntu-warty-x86; now I have installed
Kubuntu-breezy-x86_64), so it should be possible to get things going
again.

If this is not an open technical support mailing list, I apologize for
troubling you.  Also if this is a known problem fixed in CVS, again
sorry.  For now I'm using the binaries that come with Kubuntu, but I
plan to eventually switch (back) to a self-compiled system.

Here's an excerpt from my Xorg.0.log:

Thanks in advance for any help you can offer.
