And thanks for putting up with Gareth ;)

Sure.

I'll try to keep on eye on the technical discussion (looks like it
moved to current at freebsd.org), but please keep us in the loop.

For the short term, I'll probably leave the NVIDIA libGL as is
(hijacking %gs), and document it as such in our README.  Once the
TLS decisions are worked out on FreeBSD, we'll propogate the
appropriate changes to the NVIDIA OpenGL driver.

Thanks,
