vmware and qemu (open source semi-alternative) are good ways to
accomplish booting Windows from inside of FreeBSD.  What you want,
however, is something that has been on the wishlist for a little while
now.  Suspend-to-RAM has been around and works fine for a while, but
Suspend-to-disc (which Linux currently has) is yet to be written. 
There have been suggestions of saving the RAM to swap space and
shutting down.  I hope to see someone put this into action soon.  It'd
be a great feature.  (Especially for mobiles)
