i had same problem - fujitsu laptop with ich6 sata controller but with pata disk putting it into 'legacy/ide' mode. ahci module would drive the controller/disk but suspend didn't work. removing ahci module and adding ata_piix module resolved this issue for me, now i get full s3 suspend as well :) device naming stays the same so you might just get away with removing ahci module and redoing mkinitrd.
