I don't have benchmarks but I know how much better (faster) matroxfb _feels_ than vesafb on a Millennium II. AGP, that is. And the CPU isn't exactly slow either ;-)
On a completely unrelated framebuffer issue: I have a simple program which swaps colormap entries to give me a black-on-white screen. (Which isn't exactly the same as the "inverse" option, because that swaps foreground and background, so if I set text to display in red I get black-on-red instead of the desired red-on-white.) My problem is that the palette is reset to the default on every console switch. I'd like to have it persist across switches, but I don't know how impossible that would be. Comments?
