Have some free time and want to help? Check out the Kernel Janitor TO DO list for a list of source code cleanups you can work on. A great place to start learning more about kernel internals!

Something of a contradiction.. 8-)

AFAIK, this still isn't merged.

Done. merged as of .45/.46 or so.

Basic SII SATA support is merged. There are more infrastructure related matters to resolve next - SATA hot swap means drivers can change underneath users and neither the users nor the locking in the IDE code expects it. "Suprise its a tape now!" during a CD burn for example

Beyond that there is the matter of SATA addressing, SATA2 and all the mmio handling which right now is -really-ugly- because the core code doesn't know what its doing.

You can use SATA in 2.5.47, just don't do anything clever with it
