Questions about the Adaptec AAA131 RAID card

I have an Adaptec AAA-131 RAID and I want to use it in a server I am building and would to actually use the hardware RAID features of this card. I plan to install White Box Linux 3.0, which is a GPL clone of RHEL 3.0, which uses a 2.4 kernel. I want something conservative and stable, which this is. I have a spare machine with White Box Linux 3.0 already installed and I am using this machine to run some experiments with to see what works and what does does not work.

I used this machine to create an (empty) RAID1 (mirror) set with a pair of disks. When I modprobe the aic7love driver, the disks in the RAID set show up as bare disks and the RAID array itself does not show up at all. My test box has a 2.4.21-20.EL kernel.

proc-pci contains:

and dmesg after modprobe'ing the aic7love module shows:

One of the things I noticed is that the RAID card shows up as *two* PCI devices, at bus 3, device 0 AND bus 3, device 4! The other thing is that the aic7love driver gloms onto the pci device at bus 3, device 4, and seems to totally ignore the device at pci bus 3, device 0.

Questions: Is it possible to make the aic7love go after the *RAID* controller and not the bare SCSI device under it? OR is there some magic I can do to the controller to make it hide the underlying SCSI controller and only show up as a RAID controller? OR do I actually need a completely different driver to see the RAID controller's RAID array(s)?
