What results are perceived would depend on the work load.

That said, the slower the clock of the system the longer the resulting
latency from executing a given kernel operation.  Thus, a preemptible
kernel on the dreamcast can offer significant advantages.

I would wager you would see a nice benefit in interactive performance
under load on the dreamcast; but then again, I would think you would see
that on your normal machine, too.
