One argument for my patch was: Not register at all the "ram"
save/restore function when Xen is enable make the code more clear: no
ram saved with Xen.

On the other hand, unregister the "ram" save/restore function in the
Xen code, will remove this if(xen) from the generic code.

I'm fine with both.
