    Oh come on, how hard is the following?

    You have tons of flexibility you are ignoring here... For the
    non-hotplug hosts (ie. present at boot), just use pci_driver::probe to
    register hosts on a list, and little other work. do_deferred_work()
    handles the list in a manner that ensures proper boot and/or host

    So for non-hotplug hosts you do a init_module time:
    register N hosts with PCI API
    register N hosts with SCSI API

    And hotplugged hosts would do the same, with N==1.

    What you describe -is- supported with the PCI API.
