We've mostly been working on getting familiar with Xen 3.0 for doing  
the x86_64/Xen port. One of my students, wrote a Xen minios for  
x86_64/Xen to make sure he understood Xen well, and is now moving on  
to the gcc 4 port. Hopefully things will be working there relatively  
soon, but not yet. We'll probably working from a crosstool toolochain  
build so its relatively easy to do the toolchain build from source if  
you've that masochistic.
