At least, I thought it was in Greg's tree, not sure now.. This is the patch in -mm:
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.24-rc6/2.6.24-rc6-mm1/broken-out/pci-disable-decoding-during-sizing-of-bars.patch
Without this change a bunch of machines fail to boot even without the MCFG change (since their MCFG was E820 reserved and so the old validation check passed).
