How to get yum to only install < i586?

[seandarcy]

I'm running fc6 on an old i586 machine. yum updates the kernel 
correctly, and glibc.

But, it continues to install openssl.i686, which cause no end of 
trouble, because this a remote machine. openssl.i686 hoses sshd and rpm. 
  So someone actually has to crawl though a long shaftway, and set the 
machine to allow telnet.

I have exactarch=1. Somthing I'm missing?
