The only methods used by Windows are the keyboard controller, the ACPI 
registers and (according to your results) the EFI reboot mechanism. If 
none of those work under Linux but Windows is able to reboot 
successfully then we don't need to add new methods, we need to find out 
why the existing methods don't work.
