In XFree86, 32 bit framebuffers are not generally better. In most
cases, 24 and 32 bit framebuffers only display 24 bits of color (which
is why XFree86 recently started using the term 'depth 24' for these
modes, to help reduce confusion.) In some cases, 32 bit framebuffers
are slower, and they always consume more ram because the 24 color bits
are packed less densely (into 32 bits of ram).
So, the moral of this story. Pick your favorite resolution at depth 24
for the best color on your card. For more speed, using depth 16 is a
good choice on most cards, while still supporting high color
combinations. (depth 16 matches Windows hi-color/16M color
nomenclature, depth 24 is true color.)
