The stock kernel (2.6.8-1.ydl.7) will NOT boot a OldWorld. 
It will hang at a mon> prompt shortly after bootloader. The kernel from
 shiner.info: <http://www.shiner.info/?manuals/ANS-from-3-to-4.html>
will work just fine as well as the latest kernel from TSS (2.6.9-1.ydl.8).
Use shiner's kernel to install via anaconda then upgrade via yum.
