we have the same specs and booting works fine for me, but mind you that i used the USB install method and i have the NUllCPUManager loading during boot time...i think that you have KP`s because there is no presence of the mentioned kext, which is required (i think) for the first boot, also try and boot the instalation with -x -v or better yet try one of the distros available like snowosx...

cheers
