My first work is here:
http://pub.haikufire.com/mesa/haiku-mesa-patch1.5.diff

This gets glsl, mapi/glapi, mesa, glu compiling with very few changes 
in
Mesa

At this point I don't think using DRI2 is do-able as it is very Linux
oriented, however I think we may be able to get things working 
(software at
least for now) by using our own external GLView within
http://cgit.haiku-os.org/haiku/tree/src/kits/opengl which simply links 
to
some key Mesa libraries.
