Currently linux-image-3.2.0-1-amd64:amd64 is effectively uninstallable
on i386 since various other packages depend on module-init-tools:i386.
However, once #649437 is fixed, module-init-tools:i386 (or rather
kmod:i386) will satisfy the dependency.
Since dpkg will prefer to install packages from the native
architecture, I don't see any problem here. I suppose I'm biased by
having actually tested this.
