Oh, so that must answers the question "Is it a keyword, or the actual

Nice trick!
I'll check what environment pygrub receive and try to find a way to tell 
it to run the original loader or give the correct values to xenpvnetboot 
or whatever.
Too bad it won't work "off the shelf", but I see it's just matter of time.
