The only chipsets supported by sata_nv driver are nForce4
(CK804/MCP04) SATA controllers:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fbbb262d9ea9bdbd79d7058271560e9990bc62d3
MCP55 isn't supported. On newer chipsets (MCP65, MCP67...)
nvidia moved to AHCI.
I think that if nobody with the necessary knowledge to support
those chipsets like MCP55 decides to program, we'll be on our
own :( unfortunately.
I searched nvnews.net forum and it seems nvidia will do nothing
about it... :(
