Thank you.  That works indeed.  *sigh*  I spent considerable
time searching the lists and google, but somehow I missed
that part in the ahci manpage ...

The only problem left is that I have to reboot when I want
to connect a device that can really support SATA-600.
But I can live with that.

Best regards
