Yeah, sorry, this is known. I will try to check in a makefile fix. DMA, if
you could do this it would be appreciated (a CVS checkout over here is a
long, drawn-out, painful affair).

Hmm, I've been using things pretty heavily on my laptop (so software Mesa
GL) with fairly complex scenes (Quake3 models), and things have been
performing just fine.

I don't know if I can offer any insights, except that I'l lbe playing with

when i'm back in town.
