If you are using an 'evaluation copy', then you also have an evaluation SUBSCRIPTION, meaning you can call them, and access their knowledgebase. You can even go to the RedHat site, type in "supported hardware" into the Search box, and read the results.
And if you don't plan on paying for RHEL, the you should not be using it. You will get NO updates/patches/bugfixes, or have access to the online repositories. Use CentOS or Scientific Linux instead.
