without seeing the hw file, i can only guess.  make sure you:
 - use unique addresses (the @xxx part)
 - are routing the output lines to different input lines
 - interrupt driver actually handles more than one input :)

i've def connected multiple Blackfin UARTs using the same model and had their 
interrupts routed independently ...
