No, actually, the 68030s are rated at 33MHz, and that's not an odd number.
The deal is, microprocessors aren't technically rated based on clock frequency,
since that's rather meaningless to designers, but on clock period.  The
frequency numbers sound better, because folks like to equate "big" rather
than "small" with "better".  In the case of the 16MHz part (16.667MHz 
actually), the clock period is 60ns.  Motorola also makes 68030s that clock
with clock periods of 50ns (20MHz), 40ns (25MHz), 30ns (33.333MHz), 
25ns (40MHz), and 20ns (50MHz).
