Try "modprobe initio" to see if that is the correct driver for your card.
You can run "dmesg" after the modprobe to see the results of the module
being loaded. If you see something along the lines of 

SCSI subsystem driver Revision: 1.00
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
        <Adaptec 3960D Ultra160 SCSI adapter>
        aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs

You'll know it loaded. Of course youse will make reference to Initio, not
Adaptec, but you get the idea. If that works, then you should be able to add
the following line to /etc/modprobe.conf:

alias scsi_hostadapter initio

If that doesn't work, you'll have to track down the right module for your
card. Google is your friend there...
