I would check the eeprom in the laptop, I would not put it past them
to have a random MAC :-), in any case it would be helpful to see what
you have there.

When you say you get a different MAC do you mean that you get the same
every time but different from the one stated on the machine or that
you get a new different MAC every time you boot?

What is in your

/etc/sysconfig/networking & /etc/sysconfig/network-scripts/ifcfg-<interface>


those are places where a MAC could be set.

Also, are you doing any KVM (virtualization) set up?
