Every 5k miles or so you can pull the bearing and clean out the housing. Pump fresh grease into the housing and replace the bearing forcing the old grease in it out.
This is true. I'm just not sure that any amount of preload will remove the play that the OP is describing. I am more than willing to be proven wrong, however.

As an aside, this option is no longer available to me on my original set of M520s since a paceline took me straight over a piece of industrial wrapping material which bound round the left pedal spindle and destroyed the bearing cap. Hence the replacement set.
