A quick glance at the BGP dissector's code reveals that it does 
recognize the capability for 4 byte AS numbers.  It doesn't appear 
though that it can display 32-bit AS numbers, only 16-bit ones.  I don't 
think anyone is working on it at this time.  Do you have a sample 
capture file that contains 32-bit AS numbers in it that we could use to 
test a new feature to recognize the new AS numbers?
