right now, the linux kernel boot will wait for this probing to be done
before mounting the root fs and then exec()ing /sbin/init.
On my test laptop this takes 7 seconds of .. nothing ;-)

the patch I have makes the kernel NOT wait for this, but just it tries
to mount root right away (and if that fails, it THEN waits and retries)
