2.6.26-rc9-git9 doesn't boot on Macintel

[Jack Howarth <howarth@bromo.msbb.uc.edu>]

   Is anyone able to boot the 2.6.26rc9git9 or 2.6.26rc9git12
kernels on a Macintel machine? On my MacBook Pro (second gen with
rEFIt installed for dual booting), I find that MMCONFIG doesn't
seem to be in use under the 2.6.26 kernels. I get the following
hang when booting rc9git9 or rc9git12...

This compares to the same section in a normal boot of 2.6.25.10...

..etc. My understanding is that the EFI in use on Macintel requires the
use of MMCONFIG so the boot failure isn't surprising but the absence of
MMCONFIG is.
