I'm getting these too. Not present in the last -rc4 kernel I built.

Reverting this commit (the only recent one to the file the message 
originates from), gets rid of the extra zero-range messages:

    PNP: mark resources that conflict with PCI devices "disabled"

    Both the PNP/PCI conflict detection quirk and the PNP system
    driver must use the same mechanism to mark resources as disabled.

    I think it's best to keep the resource and to keep the type bit
    (IORESOURCE_MEM, etc), so that we match the list from firmware
    as closely as possible.

    Fixes this regression from 2.6.25: http://lkml.org/lkml/2008/6/1/82
