--- Comment #8 from Ilia Mirkin <imirkin at alum.mit.edu> ---
This patch should get it going, but I don't think I want to commit it as-is.
This gets me the same overly-lit rendering as r600, so any remaining issues are
in the st. Should probably investigate what the "real" rendering looks like,
neither lighting matches any screenshots of the game I've found online.
