Doubled buffered dumbtest runs at 535 fps here (on my trusty TNT2).
On a GeForce2, it runs at 1000+fps

I think this is not insignificant. The Voodoo 3 may be the factor in the 
speed, because on all other cards, dumb test runs above 100fps at least.

This is being worked at, however, both Matrox cards and NVidia cards seem to 
display this correctly (mine and George's). Can you build the debug version 
of the lib and send me the generated allegro.log from exalpfnt?
