Leon,

you are right, the meaning of "clocks_per_usec" may be missleading. But
the bus clock is not the CPU (execution) clock either. Since the 603 has
a CPU internal PLL, the CPU clock is in most cases a (fractional)
multiple of the bus clock. So maybe we should simply add some lines of
comment to the usage of this constant on PPC.

wkr,
Thomas.
