Not possible without xen cooperation and xen has no hypercalls for this (main problem being page table layout)

I have been trying to fix grub to load a 32 bit kernel from the 64 bit
xen build.  After fixing up one or two minor issues with the elf
loader, I believe I now have it to the point where it jumps correctly
to the 32 bit kernel and it crashes there, since it is 32 bit code
still executing on a cpu in 64 bit mode.  The question is how to
return the cpu to 32 bit mode *under xen*?
