I also want to like to know more about SATA support. I understood well, MorhpOS on Powermac wouldn't even work with one of these cards installed ? Or can I already use such a card now with MacOSX on it ?

Reason I ask is that I want to learn more about MacOSX before I buy an Intel one and replace my now 6 years old windowsXP box that doesn't want to run windows7 because a certain nvidia chipset isn't supported ( it already wasn't in Vista ). So it would be fine I can put Leopard on a SATA drive without touching the drives I use for MorphOS.
