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@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,
