It works!

Here's the relevant output from dmesg:

I know it says up there it's "2422" but I'm sure I've read from the BIOS
messages it's "2462S". Anyway, not a big problem.

I'm not familiar with this hardware, but I'm curious why I see the one
test drive I assigned to it twice. I seem to recall reading somewhere a
discussion for Linux in which it's been mentioned that one of these
should be a read-write and another "read-only" device, but is this
correct? I can write to both drives.

There's something else that bothers me: I'm using GEOM_LABEL and, at
least in theory, there might be a problem when the same label is
detected on both drives. AFAIK, currently this event is handled so that
the second label gets ignored, but who knows for the future?
