I ran into this installing Ubuntu on a friend's machine (the newer MacBook 5,2 http://en.wikipedia.org/wiki/MacBook#Model_specifications released May 27, 2009).

Potentially helpful information: https://playlegalsportsbetting.com/

Someone found that /proc/cpuinfo reports the CPU as being single core, even though it is actually dual core. From https://bugs.launchpad.net/ubuntu/+source/linux/+bug/341230

When booting without any of the options as a workaround for this bug, the screen goes blank and for a brief moment i see "[5.162415] Not responding" before the screen goes blank once again. I uploaded a video of this to http://www.archive.org/details/FuckingMacs but it is temporary and will disappear after a few days. Anybody know a better place to host?

How can i help? What other info is needed for this bug?
