[CentOS] SCSI controller setup

I have an IDE based PC running Linux/CentOS4 to which I wish to 
attach a scsi dlt.  The host controller is an Adaptec AHA3940 
something that lspci reports as:  
SCSI storage controller: Initio Corporation 360P (rev 02).  

I would like to have the system load the driver for this adapter at 
boot but I have two problems: 1. I am not sure which driver to use; 
and 2. I do not know how to force Linux to load a driver module.

My research to date indicates that the driver module for this 
device likely is one of:

/lib/modules/2.6.9-11.EL/kernel/drivers/scsi/aic7xxx/aic7xxx.ko
/lib/modules/2.6.9-11.EL/kernel/drivers/scsi/aic7xxx/aic79xx.ko
/lib/modules/2.6.9-11.EL/kernel/drivers/scsi/initio.ko

My reading of man modprobe.conf and modprobe lead me to conclude 
that the following needs to be added to /etc/modprobe.conf

install <name of one of the above drives>
alias scsi_host_adapter <name used for install>

Can somebody confirm whether I am on the right track or not and 
provide some advice has to how to proceed? Which is the preferred 
driver for this card?  Do I have to make additional entries for the 
tape drive itself an HP surestore dlt vs80?  How do I create the 
necessary /dev/st# and /dev/mt# entries?  Is there a Linux utility 
program like kudzu that can probe the hardware and automate any of 
this?

I am a digest subscriber so replies that only go to the list will 
reach me in about 24 hours.

Regards,
Jim
