Comment(by hvr):

 What about the variant below? it compiles with GHC 7.4 and seems to
 work...

 {{{
 #!hs
 {-# LANGUAGE MultiParamTypeClasses, FlexibleInstances #-}

 import Control.DeepSeq

 class Monad m => NFDataM m a where
     mrnf :: a -> m ()

 instance (Monad m, NFData a) => NFDataM m a where
     mrnf x = rnf x `seq` return ()
 }}}
