Well, afaik that wasn't BeOS's Problem since R5 anymore. But the drivers where missing.
I think a good, optimized Software GFX-Plugin will do his job good.
On other platforms like the PSX, there a softwareplugins that work very well.l. For example for ePSXe. So it should be possible to create an optimizted Software GFX-Plugin.
But it's good that it's planned!
