Would you mind sending me hdparm -i /dev/hdx and hdparm -I /dev/hdx for documentation purposes? The host controller chip could be the one to blame as well.

I fear the need for jet another black list.

Here they are. This is with i845 (82801BA rev B5) host chip. I'll check i440BX tomorrow and PDC20265 on sunday. I believe that PDC20265 worked because of I did not notice problem at home, only at work.
