Ubuntu Breezy modifies glxgears so that no FPS rate is output unless "-iacknowledgethisisnotabenchmark" (or something similar) is passed. I think this'd be a great way to stop a lot of the useless comparisons. If people think this is a good idea, I can provide a patch against xorg-x11 and glxgears (once the ebuild exists for modular).
If upstream accepts the patch, so will we.
Please file this at bugs.freedesktop.org, xorg product. Or possibly mesa product. Post the URL here once you do. Thanks!
I posted this under the Mesa product, as that's where your glx-utils ebuild seems to grap glx{info,gears} from. https://bugs.freedesktop.org/show_bug.cgi?id=4704
