OK yes I understand the theory. And now that you mention this, I've done some tests. Your theory is correct on dual-core systems. I've tested my laptop with some OpenGL games: Quake 3, Sauerbraten, Frets On Fire, Stepmania, Tux Racer, Armagetron. They performed quite nicely, the CPU load was distributed among the 2 cores. The problem begins when I test the same games on a single-core system. The CPU goes up to 100% with almost every game. That's right, it's not just glxgears (everything what you've said is true about it) Anyway, it seems like the Ubuntu kernel is somehow optimized for dual-cores. This can still be considered a bug.
