You've got to re-make the initial ramdisk, with the following in

alias scsi_hostadapter aic7xxx
options aic7xxx aic7xxx=reverse_scan:1

The 39160 card is getting picked up first by the aic7xxx driver - you need
the onboard chips to get picked up first.  Make that change, then remake
your initial ramdisk, and you'll be fine.
