Serial port interrupt woes omitted..

If you are really strapped with this problem, try replacing the USART chip
with a 16550 and enable the FIFOs.  This can provide enough help to overcome
the interrupt latencies, assuming that your interrupt routines are already
clever enough to check for more data before exiting (DO this first if you
have not yet tried it!).
