Serial Driver and IRQ0

The standard Linux serial driver uses an IRQ number of 0 to indicate a port
has no interrupt - but UART0 on a 4xx is on IRQ 0. Therefore interrupts are
disabled for UART0 (ttyS0).
It's easy enough to hack the standard driver to work around the problem, but
is there a more elegent solution? I can't believe nobody has had to deal
with it before.
