Personally I was thinking about adding really basic stuff that releases the 
CPU from drawing GUI related stuff. Like drawing lines and (filled) boxes.
Just implementing these two functions should reduce CPU overhead considerably.

Cool, is the system working? What are you doing with it? Are you running 
uclinux (or similar). If so, did you write a device driver for the vga 
adapter? I am asking this because I still need to write a device driver for 
it. You work might be a good starting point.
