There are, however, cards that will use four bytes per pixel even at
24 bit color depth due to memory alignment requirements. On the other
hand, as there's no 1.5 MB graphics card (that I knew of), this is
irrelevant for the 800x600x16M mode, which will require 2 MB of memory
anyway. It will make a whole lot of a difference for 640x480x16M, though.
