The codes used for this auto-probing is relatively small and easy, so
as Rene expected, I don't mind about it :)

The criterion is only whether it's _really_ useful and works without
hitch.  We keep the old code as is just because it was worked, and we
shouldn't break it.  The concept is not perfect, but if it practically
works, I have no objection.

I'm for merging it -- at least, if it's confirmed to work on the
latest kernel (and the bug is fixed).  Let's put all them in a pot
before 1.0.15 final. We'll cook better after that.
