USB 3.0 support on RedHat 5.2

We are trying to qualify RedHat 5.2 on new HW platform. Unfortunately the new Motherboard comes with USB 3.0 and RedHat 5.2 does not have USB 3.0 support.

Is there a possibility of getting the USB 3.0 code from RedHat 6.0 and compile it in RedHat 5.2 ? What is the risk involved with this ?

We are trying to upgrade to RedHat latest version but that is a long pole and we want the USB 3.0 support in RedHat 5.2 ASAP... Any suggestions on this is well appreciated.
