With 64Bit hear why not drop all the legacy in it. Like someone said Microsoft could provide a trimmed down VirtualPC with a preconfigured WinXP for all the legacy stuff. New 64Bit drivers have to be written anyway so that solves that problem. All the applications have to be recompiled or rewritten for 64Bit. It seems logical to me. Now is the perfect time to get rid of all the legacy crap.
