I took a drive from an ailing machine to suck the data out of it. This
drive used to be part of a single drive LVM. Now, when I connect it to
my machine, I realized I had named that vg the same name I had used in
the vg I have in my desktop associated with just one drive,

VG UUID fjM9qy-aCEM-iluj-yTdQ-CwT5-Iijk-uOYXlB
We see that UUID fjM9qy-aCEM-iluj-yTdQ-CwT5-Iijk-uOYXlB is the drive/vg
in use while UUID SB3NfW-swQM-5rdw-xf5e-z6At-r5DM-dUwG7D is the extra
drive I just attached to my machine. So I thought on using vgrename to
change the name of the extra drive's vg so I can mount it:

What am I missing here? I thought if I told it to rename the vg with a
given uuid I would be golden. As you can see, that is not the case.

What version of lvm2?
Try a newer one in case it's something we already fixed.
(An entry in 2.02.63 changelog might be relevant.)
If it still fails on the latest upstream, obtain output with
the -vvvv flags and post a link to it.

I do not know how ancient it is, but it seems that is the one that is
currently available as a package for ubuntu 10.10

The HD in question has a VG that is a few years old (and done in centos
4.7).

I think you need to make the vg unavailable before you can rename it:
vgchange -an SB3NfW-swQM-5rdw-xf5e-z6At-r5DM-dUwG7D
then your vgrename should work.

There is a vgimportclone script posted to this list, and added to recent
LVM sources, that handles the situation where the UUID is also identical
(due to hardware cloning). Since you have distinct UUIDs, there is
something we are all missing.

When I run into things like this I go for the Live CD or Live USB
stick and boot to it. For your specific situation I would disconnect
the new drive and boot a live version of your disto (I'm not sure if
you've said what your running) or if that's not practical get a copy
of System Rescue CD[1] and boot it.
It will probably activate the volume groups by default so you'll have
to go through, "vgchange -an /dev/export" then do the "vgrename ..."

You could try using vgimportclone, eg:
vgimportclone -n newvgname /dev/sdb
(replacing /dev/sdb with your new device name obviously)
vgimportclone works by setting up its own little lvm environment where only
/dev/sdb exists so it shouldn't get confused by the preexisting VG (which
presumably has the active LVs that are causing lvm to get confused)
Doesn't explain why it doesn't work in the first place though
