Just as a point of interest, bit addressability does not win in certain
graphics environments; there are planar, chunky, and chunky-planar graphics
organizations (probably there are more, but I am not a graphics type),
and in chunky, bit addressability gains very little.  For 8-bits per
pixel in chunky, byte addressability is wonderful.  For 24-bits plus
alpha, 32-bit word addressability is great.  This is according to the
graphics guys here.  BTW, the TI 34010 is none too fast.
