Yes, as long as you don't have a 32bit kernel also in /lib/modules/* of the same version. > If so what other utilities on the system NEED to be 64bit for this to > work?

You'll need to get an x86_64 compiler on your system (crossdev should work fine, or you can modify gcc64), then you'll need to cross-compile the kernel (there are plenty of docs online about how to do this). --Jeremy
