Support of AMD64 architecture

Dear All,
I used cran2deb in the past quite happily. I am now running debian 
squeeze on one of my machines (amd64 architecture) and planning to stick 
to it even after it is released as the new stable.
I now read at

http://debian.cran.r-project.org/

that the amd64 architecture is not supported right know. Now, seen that 
cran2deb has always been extremely convenient to me, I would like to 
know if someone has any idea about when the amd64 support will be resumed?
Many thanks

Lorenzo
