Because perfmon handles the modal register and it has code in it to check for different CPUs etc. At any rate, Dyson just posted his way of enabling write combine for the frame buffer. To David, Hi Dyson, just posted a way of enabling write combine on a vga frame buffer. What do you think is it something that the XFree86 team can tackle? We can of course take care of it in the form of freebsd however I think it will be best if Dyson's method is somehow incorporated into XFree86. Tnks!
