You have the right idea, and you are correct in that it is not simple.

If you run your desktop in dom0, everything should work (assuming 
correct kernel config).
A good place to start for packages might be:
http://lists.xensource.com/archives/html/xen-users/2005-08/msg00765.html
but those links don't seem to be up.

If you want you can compile and install from source, but remember to 
always use "make ARCH=xen" when in xen-{2.0,unstable}.hg/linux-$version 
directories -- that includes menuconfig and compiling.
As for xen versions, 2.0 is working great on a server for me and I 
haven't tried unstable yet (soon to be 3.0).
I guess that the bottom line is that if you want to get your hands 
dirty, then jump right in.  Otherwise you might want to wait for distro 
specific packages.
Hope that helps,
Jeb
