Hmmm, it doesn't work for me.

The port builds and installs, and it's even recognized (apparently 
correctly) in about:plugins, but attempts to view the page at 
http://www.java.com/en/download/help/testvm.xml result in the java and 
the browser hanging, eating CPU cycles as if looping:

This is 8-STABLE, amd64, Firefox 3.6.3

about:plugins says:

     File: IcedTeaPlugin.so
     Version:
     The IcedTea NPR Web Browser Plugin (using OpenJDK6 b20) executes 
Java applets.

followed by a table of MIME types for applets handled by Java.

Console output of Firefox contains this trace:
