Grub Gurus, Many thanks for your prompt replies. I realize my knowledge gap had more to do with the processors than the loader. I found the following link helpful: http://www.techsupportalert.com/content/32-bit-and-64-bit-explained.htm Sorry if my question was off topic but glad to know it is not a problem to run mixed width O/Ss on the same hardware.
