This is the out-of-the-box configuration of a brand-new vaio laptop.
But it's not "connected to the secondary slave" as you say. Rather, it's
connected as a primary master to the second (S)ATA controller, which shouldn't
be a problem. The real problem here is that this second controller isn't
being recongnized for what it is, namely a '82801FBM ICH6M SATA Controller'.
The ata driver therefore falls back to "GENERIC ATA controller". Hence the UDMA33.
