Comment 34 for bug 885324

On Ubuntu, we'd like to migrate everything away from liblcms1 by 12.04, which means this would need to be done in the 1.4 timetable.

At a distro level, supporting 32-on-64 lcms2 is just as easy as lcms1. On Ubuntu 12.04, for instance, it's already multiarched and you can just apt-get install liblcms2-2:i386. So I'd expect it to be quite available.
