you're right, I had missed the mirrorlist entry in rpmforge.repo

I don't know where that $ARCH is coming from.

/etc/rpm/platform should have

is this what you set it to?

If you can't find the solution you could always hardcode x86_64 in 
/etc/yum.repos.d/mirrors-rpmforge and make mirrorlist point to that.
