40p support broken since 3.99.22?

Does anyone use recent NetBSD versions on 40p (aka Sandalfoot,
6015/7020) machines?
After experimenting with NetBSD under qemu/PReP it looks to me like
the 40p support got broken quite some time ago with this commit:

    Completely rework how we look up PCI interrupts on prep:

    1) Rather than build an array of the pci->intr mappings, build a proplib
    2) add a SIMPLEQ of device properties to the pci_chipset_tag to hold the
    proplib trees of each bus.
    3) Move the interrupt routing code from pci_conf_interrupt to pci_map_intr()
    4) Deal properly with non-native PCI bridge chips that are not recognized
    by the prep firmware, and therefore are not noted in the residual data.

    The major win of this restructure is #4. Hopefully I haven't broken
    anything. Tested on a 7248-100, 7043-140 and 7024-E20.

^^^ the SIMPLEQ called from the pci_intr_fixup_ibm_6015 causes a null
pointer dereference.
