Patch from Brian Smith (modified a little by me) to allow kernel config
file override to disable fifo on 16550s:

I bought a board with two 16550's, but one of those ports has a mouse
on it.  The sio driver always enables the fifo, which is a bad thing
for mice and X.  The mouse is jerky and hard to use.  The simple thing
is be to treat one of the ports as a non-fifo'ed UART, and I use the
flags option in my config file.

So, my config file has:
device      sio0    at isa? port "IO_COM1" tty irq 4 flags 0x2 vector siointr
device      sio1    at isa? port "IO_COM2" tty irq 3 vector siointr

(patch deleted)
