Yes, we are talking about x86_64 in 64bit native mode.

I needed a small patch to build the sablevm-classlib package for 
the amd64 architecture (see below). A few other packages needed similar 
small patches. I did not find any serious obstacles for a x86_64 native 
64bit port.

There is an almost complete port of the Debian system to x86_64 in 
native 64bit mode (including a libffi). However, there is no 'official' 
archive for this port yet. I hope this will change soon.
