It is disabled by default, in the config; and Paul/Balbir already
provided the cgroup_disable=memory bootoption to override that.

Is it wise to add an additional hurdle now that 2.6.25 has gone out?
Is it wise to switch it around in future?  Seems a source of confusion
to me (I already wasted time testing the same things twice in -mm
because of this).

I guess Andrew needs to make an executive decision!
Whichever way round, we ought to clarify the config helptext.
