Have you tried installing Ubuntu using rEFIt? Link: https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation (the dual-boot section)
Before installing, read these topics before installing. It explains a possible reason for this problem and a workaround by installing the bootloader to the same partition as Ubuntu instead of replacing the Mac's own bootloader. After this you can either use rEFIt to boot into Mac OS X or Ubuntu, but I've seen discussions that some people who have created the partition for Ubuntu using Bootcamp, go to the boot menu by using the 'option' key and selecting the Windows icon, but I haven't tried that myself.
