SCSI Zip drive questions

Hello.
I've got a SCSI Zip drive which I'd like to use on a 5.4 box. So far it
works with two minor problems:
a) I'd like to be able to mount it as my day-to-day user. So I put
myself in the operator group; added the following to /etc/devfs.conf:
own /dev/da1 root:operator
perm /dev/da1 0660
own /dev/da1s4 root:operator
perm /dev/da1s4 0660
Then the following to /etc/fstab:
/dev/da1s4 /mnt/zip msdos rw,noauto 0 0
The issue here is that "mount /mnt/zip" will fail because /dev/da1s4
does not yet exist. First I need to try and mount /dev/da1, then da1s4
will be created.
Is there a way to automate this?
b) It's *slow*! The same hardware with a different operating system
(OS/2) gave almost twofold performances! Copying a 90MB file to a zip
drive takes more than 10 minutes and it didn't with the old software.
Is there a way to improve this?
Here's the relevant dmesg:

The errors should be normal, since the drive was empty on boot.
