It would be really nice if the new distributions could have both drivers in bears so you can choose. I will be happy to test for you.
We're being very strict in 7.0 - the only drivers included are the ones in the CentOS kernel. We simply don't have the resources to maintain the kernel package, and add-on drivers have caused us a lot of pain in upgrades in previous releases.
I suggest you raise a bug at the bugzilla.redhat.com bug tracker to get the updated drivers into the base kernel.
If someone feels like maintaining a repository of updated drivers on contribs.org, that would be a great idea.
