	Very interesting and thanks again for the excellent explanation
Robert!

	Ps: I imagine how many people are running their servers or
desktop computers using the legacy PIIX driver, just because the BIOS
setting is wrong (IDE instead of AHCI). In my case I just ignored the
"RAID mode" option because I don't ever use RAID.

	Don't you think it would be nice to add a warning message
when the kernel detects  AHCI capable system like ICH10 and the kernel
is misconfigured using the legacy PIIX driver? It could be
something like that: "AHCI capable chipset: use ahci driver instead".

	Ps2: sorry sending 2 times (forget to send to the list)
