I feel _really_ stupid about the cause of the problem.... I hadn't set up
the interrupt mapping of the serial ports in my board initialisation
routines in U-Boot. Once I mapped IRQ4 to UART0 it all sprang to life ;)
Big thanks to everyone for helping and a big thanks to all the linux and
GNU developers for creating such a wonderful 'toy' ;)
