Alright... simply to get it into the archives so it's earchable I am 
going to submit the solution I finally came up with for this. I got some 
help from a nice user in the #xorg channel on freenode and I have it 
working now. Attached is my xorg.conf file. Hopefully it may help 
someone who has the same issues.
