While busy-waiting for completion, check the hardware after scheduling; don't schedule and then immediately check the _timeout_. If the yield() took a long time (as it does on my OLPC prototype board when it's busy), we'd report a timeout even though the hardware was now ready. This fixes it, and also switches the yield() for a cond_resched() because we don't actually want to be _that_ nice about it. I see nice tightly-packed SMBus transactions now, rather than waiting for milliseconds between successive phases. Actually, we shouldn't be busy-waiting here at all. We should be using interrupts. That's an exercise for another day though.
