[conspire] Mixing Squeeze / Wheezy

[Paul Zander]

A while back, I installed Wheezy in place of Squeeze on older laptop.  A primary motivation was getting new versions of assorted packages, such as GNUCash.  It also lead to learning lots about desktop environments: Gnome, KDE, LXDE which were topics of assorted email threads.  

Now with things reasonably "stable" using the "testing" release, I noticed a message that was previously ignored.  It advised going to linux wireless and downloading a particular driver so that WiFi would work.  And after following several steps of re-direction, I determined that what I should do was:

aptitude install <driver_installer>  
It didn't work. 

aptitude search <driver_installer> 
Didn't find the package.

Well the Debian package lists includes the desired package in stable not in testing.

I am vaguely aware that there exists a way modify /etc/apt/sources.list to include both, but I can't seem to find the details so that the package manager won't get confused.
