What I/O addresses are we talking about here? There is someone working on a SD/MMC (blah blah) memory card interface that is on LPC, using what used to be reserved as timer IO ports (0x40 - 0x5f), and he's splitting timer ports up into 2 ranges: 0x40 - 0x43 and 0x50 - 0x53, so that the LPC ports are available.

We have isapnp, biospnp but not great acpi pnp. | None of them help because you need to deal with hotplug.
