Some updates to the SATA core (libata) are required to support SATA-II 
drivers.  These updates (attached for 2.6.7-bk20) just change internals 
only; no behavior should change.

Testing is requested, to make sure I didn't break anything.  Tested 
locally on sata_sil, ata_piix, sata_promise, sata_via and sata_sx4.

These changes are found in the libata-2.4 and libata-2.6 queues (BK info 
below), and also in patches for 2.4.x and 2.6.x:
