But are the packages also compiled for the 64-bit architecture? For most packages it probably won't matter much. Maybe this is the right answer: http://ubuntuforums.org/showthread.php?t=785743 I'll also have to make sure that Oracle will run on that system before I buy it (I think I mentioned before that I'm stuck in Oracle world for now but may go to PostgreSQL someday).
