    I read somewhere that there wasn't a specific reason for not allowing
    device polling and smp to be used at the same time, and that it was fairly
    safe to remove the #ifdef SMP/#error block in sys/kern/kern_poll.c and
    compile in both smp and device polling.

    I haven't done this in a production environment, but I've done it on my
    smp desktop box, and it seems to work okay.
