I can report that the AHCI driver is working successfully for me.
My new PC is a Dell Precision 380, with a single SATA drive.
I have successfully installed Solaris Nevada Build 57 from file
"sol-nv-b57-x86-dvd.iso"
onto the PC, and it is booting from the SATA drive and functioning without
problems.
In the BIOS, for the setting "SATA Operation" I selected option "RAID
Autodetetct/AHCI"
which Dell describes as meaning "RAID if signed drives, otherwise AHCI"
