I am running 64-bit Ubuntu 10.04 on my MacBookPro5,1 using rEFIt and GRUB (Ubuntu stock version, 1.98). I didn't do anything fancy like using an EFI GRUB or adding special kernel parameters. I get full use of both cores. I'm not an expert on the Mac platform so I don't know if rEFIt is making it work for me or whatever -- all I can say is that it works fine for me this way. Regards, Colin
