I'd completely forgotten about that.
Metacity is in the process of adding a 3D option (like compiz) so that you
can do 2D or 3D without switching to compiz.
Metacity-3D, like compiz, requires a decent graphics card, and presumably
that gconf switch lets you turn it on at the moment (compositing ~= 3D).

If it worked in Intrepid/Jaunty then it should probably work in Karmic -- I
don't think there were any major changes to compiz this release, though I
wouldn't quote me on that.
This means it may not actually be a bug in the auto-detection.
It may simply be that there is something wrong with the driver for your card
that isn't exposing its full capabilities properly.
If you've already filed a bug against the auto-detection then it's worth
raising this possibility in a comment at least.
Also, please post a link to the bug here, as any further discussion should
probably happen in the bug rather than on this list.
All the best,
