A more detailed explanation of why the PCI bus manager needs resource assignment and what it is might help inspire or motivate someone to take up the task.

I may be mistaken, but I believe it's mainly for the case of systems where the BIOS only takes care of assigning resources for the bare minimum devices needed to boot, and leaves the rest to the OS (I.e. the "PnP OS" setting one sometimes sees). In such a case, the bus manager needs to take care of resource configuration for the remaining devices in order for them to be usable.

Sounds familiar. Is it still valid? was this for non acpi compliant systems?
