Ahh, a whole new chapter in the "how can a vendor screw things up" manual.

There's an argument for sending it back as faulty. It is (AIUI) a mandatory part of the SATA spec that ports will negotiate with the other end of the link and settle on a mutually acceptable speed - thus the 6G port should automatically settle at 3G with the older drive. If the BIOS/EFI firmware doesn't setup the hardware properly, then the board as a whole is faulty.

And manufacturers won't give a s**t unless they get complaints from the customers, and more importantly returns from the wholesalers which hit them in the pocket.
