Ah I am not going crazy :-)
Looks like on the botton of the board is a fintek F81216DG LPC to 4 UART 
Chip (www.fintek.com.tw/files/productfiles/F81216_V032P.pdf). That is 
why the serial ports are disabled on the SuperIO. This should be 
interesting......got a datasheet to read. Thanks for the help everyone.
