the hw virtualization (cli/sti) thing yes, but the 4MB thing not, as
GGILib lives in user-space, GGI does not spend too much time in the
kernel, rendering is done in user-space.

but i suspect things doing direct rendering like Quake could benefit from
4MB pages big time. For this we have to implement ring-0 processes though
... XFree86 is nicely accelerated (and the accelerator chip has no
business with the CPU).
