(no sarcasm intended but) i imagine the same as it runs on pretty much any other new intel-based gear, apart from the EFI stuff, of course.

i found a link to a howto the other day: http://macbook.mared.com/linux/ and it looks like it didn't need too much tweaking.

i inherited a G4 the other day and tried to install slackintosh on it but it wasn't having it. not sure why yet.
