Yes, I did a full reinstall and tested all four cases as in my last comment. When I did the UEFI install, I booted the Ubuntu 13.04 Desktop installer in UEFI mode since I was trying not to make my life too difficult. :) I forgot to mention, but the firmware version was A09 as well. I did not customize the install at all and copied the output of "dpkg -l" to check for any differences.
