Zoltan, I would be glad to be wrong here, but I understood that to mean 'Here are versions of the source code tailored for specific hardware and operating systems. Choose the appropriate one and build the driver this way...'. That is followed and qualified by the pointer to the website that certifies which kernels are certified. In our case, for instance, that is 2.6.9-67.EL.
Best wishes, Keith Arbogast
