You don't need "hardware support for maintaining the state". The configuration is stored on-disk, and the ata driver should discover it at boot time. ad_attach() in ata-disk.c (which is called for each disk at boot time) calls ata_raiddisk_attach(). If the disk isn't attached to a RAID controller, ata_raiddisk_attach() will look for a Promise configuration block, which is what atacontrol creates by default.
