The timer driver comes in two style on the pc386 BSP.  If the
CPU has the RDTSC instruction, then the CPU cycle counter is
used.  Otherwise, a counter/timer is used.

If the K6 has the rdtsc instruction, then the conditional
in pc386/timer/timer.c just needs to be changed to reflect
that it is a supported instruction.  A quick google shows
that RDTSC is supposed to work on the K6 so the macro is
too tight.

Patch welcomed.
