Have you tried using a x86_64 install DVD and going the "upgrade" route
with it (rather than the "install" route)?

I essentially did this from F6.i686 to F9.x86_64.  I had lots to clean
up when I was done, but it essentially worked.  You might have to change
the following file by hand first:

	/etc/rpm/platform

so that it contains the one line:

x86_64-redhat-linix

You might also want to change to this line in /etc/yum.conf

exactarch=0

If you do that, I think that you could then use "yum upgrade" to do the
upgrade and it would switch package architectures for you.
