Maybe there isn't a problem with Mesa, or maybe Turo found a suitable workaround. But if you go to the humblebundle site and download the updated build of Trine, the issue is resolved.
I am running Mesa from git master with none of the patches mentioned in this bug report (except any that were merged to master), and lighting is fixed. If I go back to the Trine build that was posted on HIB3 release day, I'm back to having no lighting.
Game seems to render correctly. Now, performance.... right. :)
That's odd, at least on r300g the bug is still there, and I'm using Trine 1.32.
