x32 works as far as gcc/gas/ld is concerned (at least for compiling non-trivial programs). Finding a distribution that actually *delivers* x32 libraries is another thing (and said non-trivial software uses ATM e.g. libxml2) - at least I can't find an "x32-Ubuntu". And no, I don't see a compelling reason to (try to) build the n+1. architecture for the major distributions. And yes, lots of stuff will not compile out of the box (especially if one uses a somewhat sane set of gcc options - not only -Wall -Wextra -Werror) but if one gets software to compile for i386 and x86_64, getting it to compile for x32 is a Friday afternoon job (more or less). And yes, there is enough hardware/systems out there that uses 64bit CPUs (for whatever reason - if only that one can't get a 32bit CPU for that board) but will never ever need more than 2-3 GB RAM .....
