And no it won't run in 64bit mode on a non 64bit computer. Parts of the OS and some applications will make use of a G5 if you happen to have one, but for everyday use, it's a bit like the G3's lack of a Velocity Engine aka AltiVec compared to a G4 kinda step. The only real changes in requirements for Tiger are a DVD drive and 256 MB RAM (if Panther really asked for only 128, that is, although I'm not sure about that, I guess you can still install OS X on a machine with 64 MB RAM without Classic - just like with 10.0 - but you wouldn't possibly WANT to...).
