I agree with Stefan's sentiment. It seems like this should be
the paradigm:
CASE #1: Kernel config file looks like this:
--------------------------------------------
device foo0
In this case, the kernel automatically configures stuff for driver
foo0. If the BIOS has already configured the card, and that's
acceptable, the kernel can go along. Otherwise, the kernel should
pick resources that are free and configure the card itself.
CASE #2: Kernel config file looks like this:
--------------------------------------------
device foo0 port 0x220 irq 7 vector foointr
Kernel should override whatever is already configured in the
card (if anything) with the given values.
Does this make sense to anyone else besides me? What are the
technical things that need to be done to make it happen?
