       What I did in this situation was to divide by 256 (throw away the
lower 8 bits) AND, if the MSB of the second operand was set, I
incremented the result.  This seemed to work pretty well.  An obvious
error of one bit appears at the low end (using 0x00 and 0xff results in
0x01)...  Maybe I'll mess with it a bit more...   Anyone see a quick and
dirty way to divide a 16 bit number by 255?
