Understood. That leads me to ask another question of the folks who deal
with a lot of these cards. How many could reasonably be described by the
following

		bar to map, offset, length, ro/rw, root/user, local-offset
(x n ?)
		interrupt function or null

It seems if we have a lot of this kind of card that all fit that pattern
it might actually get more vendors submitting updates if we had a single
pci driver that took a struct of the above as the device_id field so
vendors had to write five lines of IRQ code, a struct and update a PCI
table ? That seems to have mostly worked with all the parallel/serial
boards.
