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!
