There are two ways of running Debian with amd64.  Your way is the full
separate architecture approach, which has (unofficial but pretty solid)
support for sarge.  The other way is to use the standard i386 architecture
but install an amd64 kernel and the amd64-libs package, which I think is
what Ralf is talking about.
