DRI doesn't work on 2.4.0 but does on prerelease-ac5

This is a little OT for linux-kernel
Off-topic to debug a new kernel feature that will significantly add to the competitiveness of Linux on the desktop and in engineering applications?
Remember, my original report was that DRI was reported to be working in before the final 2.4.0 release, but stopped when the penguin peed on it, but now that I've done what should be done to fix this, I don't have the results that others are seeing.
While this may be due to problems with Mesa, XFree86 4.0.2, or the kernel, the fact is that in our brave new world they operate as an integrated whole so it is important to figure it out as a unit. And I'm not really trying to play quake here but QA the kernel in general - it was in noticing a discrepancy while running the Mesa test suite that I got onto this, not because I care so much about 3D performance. I've yet to find a programmer's editor where 3D performance makes much of a difference.
Comments posted here and received privately indicate that some get blazing speed from 4.0.2 + 2.4.0, and some get, well, software speeds. So there's a problem to be worked out.
I've done what others have suggested, removing any GL libraries other than the ones in /usr/X11R6/lib to make sure my applications used that one.
The build of the Mesa demos are hardwired to use the libraries from within the source distribution directories. If you take the gloss binary somewhere else, delete those libraries, and make a link to the X11 GL library in /usr/lib, gloss will run, at the amazing (and previously observed) frame rate of 7.5 FPS.
So that doesn't work.
glxinfo says dri is not available if I remove the library as I did. So I rebuilt Mesa and reinstalled it. The full output of glxinfo on my machine follows. Note that it says "direct rendering: Yes" but the version strings don't match. Does that indicate the problem?
