Well, one of the PD variants (I think it is MesaGL) compiles essentially
straight out of the box. Of course this doesn't support dgl and the speed
leaves a little to be desired. I did a benchmark of MesaGL under RiscBSD
comapred with a bottom end (as of 2 years ago) 100MHz R4600 Indy with a simple
flight simulator. On the Indy it is quite smooth. Under RiscBSD it averages
about 1 frame every 2 minutes (yes I timed it).

Anything BSD or failing that SunOS 4.1.3.
