I definitly works fine with Qlogic parallel scsi and fibrechannel and emulex fibre channel controllers aswell as lsi/engenio megaraid controllers.
It looks like aci79xx is just broken in that repsect. Unfortunately the driver doesn't have a proper maintainer, we scsi developers put in fixes and cleanups but we don't have the full documentation to fix such complicated issue. If you have a support contract with Adaptec complain to them.
