Actually, I'm pretty sure a direct upgrade will work...  I'm going to be
testing that soon though to be sure.

Odd.  My yum tells me what repo I installed from...

  # yum list installed
  Loaded plugins: fastestmirror, refresh-packagekit
  Installed Packages
  AdobeReader_enu.i486                   9.4.2-1                     @adobe-linux-i386
  [...]

Oh, wait, I just tried the same thing on one of my CentOS 5 installs,
and that third field just says "installed".

Still, the great thing about yum is that you don't need to know what
repo these things live in.  You just need to know the package names.
Well, all you *really* need is the output of this command:

  yum list installed | grep '\.' | awk '{print $1}'
