Good point! @Jeremy: Please don't mess with the partitioning layout and use the one suggested by debian-installer. Using custom partitioning is recommend only when you know what you're doing. FWIW, the disk label is automatically determined by debian-installer depending on whether the machine supports GPT or not. Unless you really messed up, it should not use a GPT but Sun disk label.
