regarding chris' bug about removing the images, there are several very relevant comments there, including some discussion about firmware updates which is not mentioned here.

Trying this with the Meerkat beta desktop livecd image (md5sum verified) I just get two numbers (1. and 2.) which look like they should be labeling some text but there is no text visible and the message to select CD-ROM boot type. Typing either a 1 or a 2 doesn't do anything. Googling revealed that some Windows beta iso images had the same problem booting on Macs; apparently in this case it was an issue that the Windows version had EFI support (and so didn't use the BIOS fallback) but was assuming a newer version of EFI. There were some other posts which claimed that it was that the iso image was generated incorrectly (something having to do with ISO9660 versions). Unfortunately, even though I develop software for a living, there is nothing I can do to help debug this (except try newer versions) since once I get to that message, everything seems unresponsive. The upshot is that a useful thing which I did frequently in older versions (i.e. boot the 64bit desktop livecd on this macbook) no longer works.
