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.
