One can do this very systematically such that you can add the repo and
it will be checked only for that package. You need to look at apt
documentation for that. This is a relatively more common thing in Debian
where can be running, say, Debian Testing and using Nvidia package from
Debian Unstable. The key is the /etc/apt/preferences file and I think
you need to look at apt pinning and also the "-t" option of aptitude (or
apt-get). All this, of course, if you want to go down this path. Not
sure how this works in Ubuntu though (mixing Hardy, Interpid, Juanty, or
even Debian); works wonderfully in Debian.
I'll definitely take a look at this.* For a one-time shot, it was easy enough to limit the package list to just the single elisp module I wanted.* My mistake was forgetting to remove the repo after I installed the elisp module.
Take a look at this:
Trust me, the dpkg from Debian is one of the best package managers I
have ever seen. And it is quite flexible while robust. No wonder
Canonical chose Debian to base Ubuntu on.

Here is what I do in such special cases. I add the repo and then use the
terminal to do the updates.
$> sudo aptitude update
then do a simulated update:
$> sudo aptitude -sV safe-update
where "s" tells to simulate only and "V" tell to show version.
If I want to install a package <package>, then
$> sudo aptitude -s install <package>
In short, use "-s" switch to see what will happen. It shows all the
details of what will or will not happen without actually doing anything.
It was easy enough to essentially do this graphically. I'll keep this in mind next time, though.
