All of that is very well understood and any kernel with least 15 years of x86 history knows how to do it. On the other hand, for getting a 64bit kernel to work with Xen, you have to jump through ridiculous holes like faking a 32bit image. Which is completely artifical and you still only get half way in the CPU init sequence. As most of the rest of the setup is *still* needed for support for ACPI S3, there is just very little reason to go to the pain in first place. Joerg
