[gentoo-user] Encrypting removable media

I have a bit of chicken-and-egg problem trying to get encrypted
removable devices to work as "normal" as possible.
Using Loop-AES and a GPG-encrypted key I had no problems encrypting my
external FW drive, but to pass all the options to losetup without
entering them by hand every time, I need an fstab entry. The drive shows
up as /dev/sda, but putting /dev/sda1 there is no good as it would try
to use Loop-AES on *every* external drive. So far I could just use
volume labels in my fstab to distinguish any number of drives---well, I
used to until hald/dbus made that automatic. But now there are no labels
any more as they get encrypted as well.
Has anyone come up with a solution for this yet? I could imagine some
plugin for the hotplug system that checks /proc/scsi/scsi for a certain
model before mounting. Not the cleanest solution either but as my
external drives are different models it would work for me. I don't have
much of a clue about the hotplug system though...

regards
	Matthias
