I'd like to second this. 32bit on 64bit works fine. I've been
maintaining separate multilib versions of the Gentoo libdrm/Mesa ebuilds
for 32bit/64bit. It is important that the 32bit and 64bit graphics
stacks are synchronised, rather than relying on external compatibility
libraries as Gentoo does currently. Failing to do so does lead to
instability and/or failure.
