biosdevname by itself doesn't rename the interfaces.  It only tells
you, given a current name, what it "should" be called.  In your case,
it should do:

# biosdevname -i eth0
eth1
# biosdevname -i eth1
eth0

The second piece is to integrate with udev.  Udev-113 (IIRC) is
required for it to be able to rename the devices on its own - earlier
versions didn't know how to rename network devices.

I spoke with Kay Sievers at length tonight, and I think I know what
needs to be done in in udev to make this work cleanly going forward.
I'll be testing that more next week.

Thanks,
Matt
