32/64 bits debs available for Ubuntu 10.04 (wtf?), Debian 6.0, and 32 bit packages available for Fedora 16 (again, wtf?) and OpenSuse 12.1.
Hopefully we get this in the partner repos for Quantal (and backported too would be nice).
PS: The 64 bit packages are still actually a 32-bit ELF, and as such need about eleventy billion i386 packages installed on amd64 boxes (multiarch).
