Anyone know more about the Serial ATA support? I had a peek at http://www.serialata.org/ and they seemed it indicate that it is a drop in replacement for parallel ATA. The FAQ explicitly states that there should be no change needed in any OS.

So what needs to be added to support SATA?

I read that Seagate will have a 60Gb SATA drive in stores next month, motherboards will be common by years end. I really don't want to wait for a 2.7 backport if SATA takes off.

Just a guess: the ATA controller will probably be like "regular" ATA controllers - it'll use the old, crufty ISA interface, which every OS supports, but if you want to use UDMA or other modern features, you'll have to have a specific driver. If Serial ATA is so similar to "regular" ATA, perhaps (for example) Intel's chipsets for it will be so similar to the PIIX4 / ICH series that Linux will use the same driver with only minor tweaks.

We shall see. And really, I have no idea.
