I have not been able to find any differences in this block between
8960 and 8074 and I have successfully tested the driver on both
platforms.

So the reason for making it more specific would be to handle any
future crazyness. Not sure what to do about this though, I have never
heard about the version numbers Stephen gave us and I can't find them
in the documentation available to us, so I wouldn't know which of the
two to select...
