To answer "the question":

You can't. And what Bryce was saying was, "You never really could".
The glxgears score was never anything more than a rough metric for 3D
performance.

The solution is to move to new tools, and test previous versions with
those new tools, and then test later versions with those same new tools.
   (this is what Phoronix does). I do this regularly. I do this by
maintaining different distribution versions at the same time. I happen
to use USB Keys to do this, but others use multiple partitions on a
single (or multiple) hard drives.

I have 8.04, 8.10, 8.10 with backports, and 9.04 on different USB keys
and test them periodically (when I have the time).

Its a bit of a pain, but I feel it is a way I can contribute.
