If you take a look on google for "CentaurHauls i686" you will see that
this CPU/chipset SAYS it fully supports i686 but it really does not.
All of EL6 is i686 and not i586 (which CentaurHauls really fully supports).
I think you are going to have issues with this CPU and EL6 forever.
EL5.x should likely be used with this CPU ...
