You could recompile the kernel for 64 bit support and run your 32 bit
userland on top. This doesn't buy you a lot though. You should
really install a 64 bit distro (64 bit kernel, 64 bit userland - I'd
recommend Ubuntu for desktop or Debian/AMD64 for servers, but there
are plenty of other choices now). Then if you still have any legacy
binary-only 32 bit apps, you can still run them, so long as you also
install any legacy libraries they depend on. Most 64 bit distros make
this reasonably easy.
