Can you take a drive from a running amd64 installation and put it into this machine? Run a make installkernel and make installworld from there and set DESTDIR to the drive of the new machine. This method does not touch anything important except of the operating system. mergemaster should not be needed as the machine is new and should have nothing on it which was not put onto it by the installation routine.
