fvdl 9b4c0e34d2 Initial commit of the port to AMD's upcoming 64 bit architecture, the
x86-64. Since there's no hardware available yet, this port is only
known to run on the Simics simulator for at the moment, and as such
uses the PC devices that it simulates for now. It will be developed
more (and cleaned up) as the hardware becomes available.
