	Well, I think that this is a good time for me to jump in and
	ask a ("theory") question that shows my lack of background
	regarding non-x86 platforms.

	In the x86 platform the xserver talks to the hardware and is
	then, able to use its capabilites (all kinds of 2d and 3d
	acceleration). But what about platforms where you have to use
	a framebuffer? Is the xserver able to use the hardware as well
	as it would in a x86?

	I'm asking this because I have a very old mac here with an
	imstt card that took me quite a while to use the native driver
	(instead of the fbdev driver) and while it is no doubt faster
	than the fbdev, I've heard that it would be quite fast. Would
	X it be faster if I used a mach64-based ATI driver (which, I
	suppose, would be more mature)?


	Thank you very much for any comments, Roger...
