CentOS - Oct 2010 - chroot from 32-bit to 64-bit filesystem?

I have a 32-bit PXE environment and I want to chroot to a CentOS x64 root
filesystem.  Of course that doesn't work.  Any tricks or hacks that would
allow me to do that?  Currently I get the error:

chroot: /bin/bash: Exec format error

What if I updated my PXE environment to 64-bit.  Could I then chroot to a
32-bit?
I use PXE to quickly troubleshoot both 32-bit and 64-bit arch.

Thanks.

Booting an x86-64 kernel with the proper config options set to enable execution
of 32 bit binaries should allow you to do that. I think.

I'm pretty sure that you can run 64 bit executables only when you're 
running a 64 bit kernel.  If you install and run a 64 bit kernel in your 
system without changing anything else, you should be able to chroot to a 
64 bit environment.
