Yes and we will get runtime errors on all mfld-atom based drivers so please
add that on all atom machines

Since the dummy symbols are present so we wont get build errors. If a driver is
using the compressed API maybe we should not add dummy so that we catch ones
which are not including this config option, so for that point I would say
removal of dummay handlers looks best to me.
