Looks like your AHA-2920 card is based on Future Domain chipset (AHA-2920A). fdomain driver was removed probably because nobody wanted to remove its scsi_module.c dependency:

I already fixed some old SCSI drivers to prevent them from being removed but such major driver modifications require testing on real HW.
