I intend to add this, as I found it is needed for another thing (bus
mastering tv cards). For mtrr it does not seem necessary, though. There
is no sense in svgalib programs setting the mtrr's. It makes more sense
to do it in the initialization script.

Not in any chipset right now. I do intend to add support for video
overlay, but nv3 will probably not be supported, as there is no info on
this (XFree86 does not support this as well).

It is under development, but acceleration is not in my todo list, and
24bpp is not supported by the hardware.
