Hmm, I was worried this might be the response :-)

Sounds like I need to look into mod_tile then.  I initially avoided it 
because it sounded much more difficult to install and configure.

I am documenting the installation steps as I go on this wiki page.  If 
anybody is willing to put some cookbook steps on this page to install 
and configure mod_tile it would be incredibly helpful.  Note that I'm 
not expecting this server to be generating tiles for thousands of users, 
my best guess is dozens at this point.  For this reason I have already 
lowered some of the postgresql settings from those provided on the OSM 
mapnik wiki page.
