For those who care, these should now be fixed in my github repo as
well. I won't repost the full series, as these are just incremental
patches, but you can see them at:

https://github.com/imirkin/mesa/commit/5eb4ad1115d0c4cb9f06a5ebb19501c1afc433bd
https://github.com/imirkin/mesa/commit/fcd6a8661ba9ac19faf205a2025b001bb31146a8

The nv50-gs branch now also contains Christoph Bumiller's patches from
late December which effectively allow us to enable GL3.3.
