Erm, I guess I see what you mean, but it comes to the effect of tying your hands now in a specific way, rather than having them tied in an unknown way later on... But I hadn't noticed the 32-bit boot protocol spec go in. Unfortunately it isn't useful for booting a pv Xen guest; I just mailed my comments. I hope we can iterate this to something more generally useful before getting too wedded to the current protocol. J
