Yep, that seemed to resolve the viewlet problems I was having. Thank you!

Apparently my package isn't the only one that a person can reach the
@@intensedebate-controlpanel url from after it's uninstalled.  I just
uninstalled Collage and even after uninstalling it I could still reach
@@collage-controlpanel with all of its config options.  I'm considering this
a non-issue for me now since other packages exhibit this behavior after
uninstalling.

The only problem I have left right now is figuring out how to move the
config options into the portlet code.  I've started moving it into my
portlet code:

http://github.com/sgraber/collective.intensedebate/blob/master/src/collective/intensedebate/idlatestcommentsportlet.py

However I keep hitting a wall when I try to use the config information in
the idlatestcommentsportlet.py.  Could someone look at the code and see what
I'm doing wrong?  I'm getting the following traceback when trying to render
this portlet:
