This (an external PATA drive in a dual USB2/Firewire enclosure) is the
solution that I have been using for quite some time now.
In fact, I'm only using the Firewire side of it and it works quite well

Yes, at least for Firewire and USB 1.1.

I have never used LVM, though. I'm only using this external disk as a
way of backup/exchange of data among filesystems.
Hope this helps, Rogério Brito.
