But, for instance, DigiBoard has 4, 8, (16?) subdevices which are distingushed in the driver in cooperation with the on-board processor. Probably would fall into your irq tree just like an hp buss device that doesn't let you diddle the interrupt sources/assignment the other side of the device/ controller. My point; Perhaps you'll need to allow for a next level tree at each EISA/ISA interrupt to support multi-port serial boards and other 'intelligent' controllers.
