I'll file a radar bug report on this with Apple but wouldn't
hold my breath for them to fix the firmware. Also, it would be
a good idea to encourage all of the folks using 2.6.26 on
Macintel to watch out for the "MMCONFIG not used" message in
their dmesg and report that to you. I strongly suspect that
the MacBook Pro v2 isn't the only model with broken firmware.
