 Okay.

 Mandriva just supplied an USB-Serial cable wich is handled by the
ftdio_sio driver. I'll port this one first, because it will allow us
to make the missing tests.

 BTW, I'll also postpone the 'libata-like' design change, because
it doesn't seem to as easy as it looked at first (note that that
design change will not impact ported drivers too much, since most of
its code are Serial Core's methods).
