Thanks for the research.  The frame rate on libGL.so.1.4.501 suggests
that it's not taking advantage of any of the hardware acceleration hooks
at all, which is probably why it actually works.

Barring a generally functional solution, any chance you could bundle the
various functional accelerated versions of libGL into the various
relevant lockers?  I'm assuming that they'll also work fine on non-fglrx
machines, but given how flaky the rest of this looks, that could be an
unwarranted assumption.  Alternately, you could include the vanilla
versions of libGL, and people could have something that would be at least
functional, if potentially slower.
