Yes, this works; however, why do you want to use 32-bit user space?  The 
general consensus is that AMD64 code is faster/better in many ways and you 
really shouldn't use i386 code on a 64-bit CPU if you can avoid it. 
(this differs from e.g. Sparc where sparc32 code is generally faster than 
sparc64 code, and so it makes sense to use a 32-bit userland there)
