  With CentOS 5.11 it's possible to get some early kernel output by 
setting the "earlyprintk=serial" kernel command-line option. But, this 
disappears when the switchover to the main console happens.

  I suspect that Centos 5 does boot, but without console output there's 
not much that can be done :( It might need some Linux kernel builds and 
insertion of debug to work out why the console settings from grub aren't 
being used.

later,

Peter.
