That is supposed to depend on how IDE-compatible your
SATA controller is. I would assume that it actually
works on some mainboards if you disable AHCI mode.

As HDAT2 works for you for spindown, does it specifically
support SATA or is it just more lucky with compatibility?

However, if you first run FDAPM and then ACPI, you
have to have 1. a cache and 2. dummy-run ACPI before
you run FDAPM. Because otherwise the harddisk would
just spin up again to load 3. ACPI for the shutdown
or standby.

As you use PCISLEEP for D1/D2 sleep, I am of course curious
whether the PCISLEEP deep VGA sleep works for you. The idea
is that graphics context is lost, but VGA BIOS can "reboot".
For other devices, I lacked inspiration how to get them out
of deeper sleep again, so for those, you only get D1 and D2.

PS: I am impressed that RayeR can reball graphics cards :-o
