I'm only aware of SATA port multiplier chips from Silicon Image.

Addonics makes boards based on some of these chips.

I have no idea about availability in Europe though.

And now to take this thread on a loosely-related tangent:

I'm guessing that SATA NCQ support could be developed
on hardware many of us already have, and would find a
wider audience waiting for it.

(This should be a larger motivation for me, but alas,
it's just not getting me started on the journey of
learning and fun.)
