A long shot, but switching to real mode does not work if the cpu is
running in VMX root mode ie on hardware with Intel VT extensions
enabled. So if you are using some kind of kernel virtualization module
on rather new hardware, consider rmmod:ing the module before
rebooting.

I'm about to post patches for kexec that fixes this problem, but I'm
not sure about the current reboot status.
