Right, I suggested this when v1 was posted. It turns out the current
kernel does not handle the compatilble list correctly and the string
selected actually depends on the order in which it appears in match
table in driver instead.
I saw there were patches being discussed to fix this issue, but until
that is fixed, we cannot really use what you (and I before) suggested.
