the 32 bit version of ghc works just fine on x86_64 if you modify it to
just pass '-m32' to all the tools. it would be nice if the driver script
checked uname -a and passed -m32 or -m64 as appropriate, so you can
trivially compile both 32 bit and 64 binaries on the same system. by
running 'setarch' beforehand.
also, ghc seems to produce noticibly faster 32 bit code than 64 bit
code.
