To address just one issue: I don't think X is slower than svgalib --
I've done a fair amount of interactive graphics work and found X faster
than svgalib in many cases. Svgalib does not provide such good tuning
of the video device for speed, and blits (from X) are often very fast.
With the DGA extension (which I've never used) X should be even faster.
If they can ever get user space DMA to work to support blits from memory
to the display, X should be even faster again.
Of course a direct access solution will always be the fastest if it's
implemented well. Maybe GGI will do that. But not svgalib, it's just
too old and rusty.
