I just lept to that assumption from the comments in the 2.4 
version

  # TODO use fdisk to figure out partitions and types

and also from the loading and unloading of the vfat module.
I should have read the script though more thouroughly.
Sorry about that.  

But, I also can't see how 
 
  ls /dev/scsi/host$SCSI/

in the 2.4 version can be made to work on Redhat 9.   But I guess 
I could merge some code from my stuff to get the same effect.

Also under 2.6 my $DEVPATH contains more than the three parts
your scripts are looking for, eg /devices/pci0000:00/0000:00:11.2/usb3/3-2/3-2:1.0
So I was a bit mystified.  Getting from the above to 
/dev/sda /dev/sdb seems to be very difficult without using
something like sg_map.  Perhaps I'm wrong to be sticking with
the old /dev/sd[abc...] stuff, and for sticking with Redhat
and its hotplug - but I was hoping that I could use 2.6 without
any major changes.  I have pretty much achieved this goal - 
except that I have to install another utility, sg_map.

The reason that my script doesn't leave mount to figure
out the file system type is because of the desire to adjust
mount options depending on the file system type. Alessandro 
Fiorino's modifications to my script uses disktype to 
retrieve the fs type and set appropriate mount options.
For example: don't bother setting uid and gid options for 
ext2/ext3 - only do this for non Linux file systems.

Cheers,
Michael
