The loader BIOS has already activated several devices. Let's do a subsystem reset before jumping into the guest. As there is no direct way of doing so, we use diagnose 308 to bring the system in a defined state. This is similar to what kdump on s390 uses. We have to define a small trampoline function that restores the low bytes to whatever the bootmap has written there.
