About breaking support for PowerPCs before G3, I wouldn't think that 
matters, since OS X only runs on G3 and later unless you use a special 
hack or something.

But if it doesn't work on the G5, then yeah hopefully it can be 
controlled at runtime and still let G3/G4 users have this stuff.

Anyone care to explain to me what this stuff we're talking about 
actually does?  :) Sorry but I dunno much about processor instructions 
and stuff.  I assume it would make QEMU faster...would it make any 
substantial difference, or add any other features?
