I just received a MacBook Pro today. I have succesfully booted the ubuntu live-cd without any issues. I'm not much of a driver developer, but I am more than happy to test things out. I'm hoping to eventually be able to use this machine as a multiboot machine, booting OSX,BSD,Linux, and maybe someday windows.

I just wanted to post my success, and offer to give machine configuration info (lspci, dmesg, etc) if it would be useful.
