    Have a base-set on first boot, then after the kernel has found
    everything run a script that goes through and adds on to the base-set
    from what is found by the kernel. You could do that after modules are
    loaded even.

    Well, at least on the i386 arch I don't believe major devices could
    be added while the system is running, I was thinking more along the lines of
    scsi drives which are hot-swappable and such.
