Well, I have read the sourcecode of the ata driver and found that there
are two revisions of that chip. For the older one there is some special
workaround. And if I remember well, that was about having two disks
on one controller causing problems. I do have the newer revision of the chip.
Up so far I have not read that these controllers do not work at all
on FreeBSD.

Yes, for sure I could exchange this controller, but unless we do a
formal announcement that this controller will not be supported in FreeBSD,
I do think that we will cause problems for FreeBSD reputation as these
contollers are fairly widespread. I am not in an urgent need to have this 
working, so I am open to help with testing.
