Its possible that I might be blowing it for the rest of the devices by 
not performing the commands that come up through the interrupts (was 
just fleshing out the driver, making sure that I got the basics down, 
and didn't write the handler meat).  I'll try adding some routines that 
look as though they flush the interrupts from the linux drivers (no 
hardware docs for the bcm440x as far as i can find).

Regards,
George
