If it definitely is a MacBook Pro (emphasis on the Pro) then it does (a lower powered 9400M and a higher powered 9600M GT - you should be able to see both under OSX which boot via native EFI) - however by default Ubuntu will boot via BIOS emulation in which case the 9400M is automatically disabled by the Apple EFI firmware or some such - BUT if you boot Ubuntu via EFI then it should see both cards.
