Upgrading i686 vs. x86_64. Just checking !

[William Case]

Hi;

I am using a *fc12.x86_64 machine.  I just now upgraded several packages
with yum (yumex) and noticed several i686 packages being upgraded as
well.  Is this normal?  Are some packages I have using i686 when I
should have only *.86_64 on my machine?  Should I remove ALL i686
packages or just leave them alone?  I am not overly concerned; just
wondering.
