Now as far as I know the order is based on which module is loaded first
and not only limiting the module but also the hardware addressing. Now
with your case AHA2940 is a SCSI card and it can not be /dev/sgX where X
is a number. On the otherhand devices you attach to this scsi card will
be assigned to respective /dev/sgX based on the above hardware
addressing resource usage etc. 


I know this is not the full answer but should give you a starting point.

What I do with scanners and cdwriters is I chown them to root.disk and I
add the user in to this group group disk has read wrire permission to
the device
