Thanks for answering!  I have loads more questions...

Okay, I think I understand.  I'd use the 64 bit kernel & modules but
the 32 bit libs, right?
How does the 64 bit kernel know the userland is 32 bit?  Won't it try
and find the 64 bit libs and freak out?
Does it use memory like a 64 bit machine?  Is there any reason to run
a 32 bit domU in a 64 bit dom0?

The reason is to do your testing, and avoid compatibility issues, with 32-bit code. This is especially important for Q/A and development environments whose software will be bundled or ported to 32-bit userlands.
