Now things are getting ridiculous...
Liferay 5.2 (Or Liferay 6... Doesn't matter)
So the gremlins came back on me with a vengeance when I started building a messenger portlet for Liferay. (Think of an internal E-mail system just within the portal. Nifty, huh? I'll put it up on Github when it's done.)
Again, using ICEFaces 1.8.1 and JSF 1.2 I went to deploy my test version of the portlet and *KABOOM* the above error.
So I checked to be sure all of my name references in my config files matched the name of the .war file. Oops! One didn't match... so I fixed that, undeployed the portlet, rebuilt and re-deployed it and...
*KABOOM*
So I went and checked that all of my class references were correctly capitalized in faces-config.xml and just for giggles redeployed it and *KABOOM*
So I went into my web.xml and commented out the listener tag to make it blow up on purpose and see what happened and...
I got a ClassNotFound error on my com.icesoft.faces.webapp.http.portlet.MainPortlet class.
AH-HAH!

Apparently when your .jars are missing Tomcat will throw an error a little different for the missing listener class than for the main servlet class, so beware.
What caused this?
As it turns out, Eclipse wasn't packaging my JSF and ICEFaces .jar files in the WEB-INF/lib folder when building the .war files. You see, I'd started this project on one machine, then moved it over to another and updated my build path references but NOT the Deployment Assembly. I don't know if it makes a difference that the project was first built on Eclipse Ganymede and now I'm working with Eclipse Helios, but either way here's how you fix it when Eclipse isn't including the .jar files you need in your output.
Right Click the project and select "Properties"
Click "Deployment Assembly"

You'll see a list of source items and the Deploy Path they'll be placed in. Make sure that all of your libraries and .jars are correct.
After correcting my .jar file paths, I was able to successfully deploy my project.
P.S. If I'd been building this thing with Maven, I wouldn't have had this trouble...
Still not working? Go on to this post.
