Dualboot Mac OS X and NetBSD on Power Mac?

[Chris Ross <cross+netbsd%distal.com@localhost>]

  I have a quad-core Power Mac G5 that I'm thinking about pushing  
into a server-class machine in the closet at some point over the next  
year.  But, for now, it's still my primary desktop machine.  So, I  
have two main questions:

  1) Does NetBSD/macppc run (well?) on this hardware?
  2) Is there a way to dual-boot Mac OS X and NetBSD, so that I could  
install/test NetBSD while still being able to get back to my stable  
and familiar OS X installation?

  Thanks...
