on an fpga?

my geforce 2 mx and intel 915 can do almost that but you need an in
kernel driver who does the actual feeding of command buffers to the
gpu on an interrupt. im thinking about a buffer mapped to process
memory and then composited by the card without any intervening system
software. the process just tells the card when the buffer is ready.
just high precision timers, no vsync and no interrupt. maybe we just
need a compositing manager to tell the hardware where the the
rectangles go on screen.
