Description of problem:

I accidentally installed the i386 Fedora Core 3 on an AMD 64.
Having noticed this, I stuck the x86_64 DVD in the machine to
see if it would "upgrade".  It said this:

  The arch of the release of Fedora Core you are upgrading to
  appears to be i386 which does not match your previously
  installed arch of x86_64.  This is likely to not succeed.  Are
  you sure you wish to continue the upgrade process?

That is, it got the architectures the wrong way around in the message.

[Of course, it didn't upgrade properly.  It would be nice if that worked,
but I'm only here to report the error message.]

Version-Release number of selected component (if applicable):
The standard Fedora Core 3 install DVD.

How reproducible:
I only made that mistake once. :-)

Steps to Reproduce:
1. Install Fedora Core 3 i386 edition on an x86_64 processor.
2. Insert Fedora Core 3 x86_64 edition DVD.
3. Boot and ask to upgrade the existing installation.
