All right, so, libata (a scsi subsystem element) doesn't support
suspend/resume at this time, at least in officialy accepted kernels.

This guy has pretty interesting stuff:

I quote:

/ACPI Power Management
/ /Fully working
/ /Suspend/Resume (to RAM) works, Hibernate works, CPU Frequency
throttling works, laptop-mode works (with fixes below)./

Especially this patch for 2.6.12.4:

http://rtr.ca/dell_i9300/kernel/04_libata_suspend.patch

I may try this tomorow...and become a very happy person. :o)

The ALPS stuff sounds good too.

I had already fixed the laptop-mode hda/sda hardcode.
