[Novalug] My personal FOSE wrap up / tues and wed

[Pete Nuwayser]

Congratulations to the FOSE team!  I suggest sending a summary to the
FOSE show sponsors:  number of volunteers, amount of swag given out,
pictures of the swelling crowds, etc... everything and anything to
help support the case for FOSE 2009.

A PC can have a "Centrino Duo" sticker on it, but it could be either
32-bit or 64-bit.  I have a Dell D630 with that sticker and it runs
64-bit Ubuntu, 32-bit CentOS, etc.  I've seen other PCs with the same
sticker but they only ran 32-bit OSs.

I agree with Greg:  a 64-bit OS will not run on 32-bit architecture,
but 32-bit OS will run on 64-bit architecture.

Pete
