That suggests to me a similar situation to a win modem or auto
resampling.
Why? The sentences above do not specify what is compared and only
handwavingly suggests a cost of "more" ... Mind you, 64bit pointers
crawling all over the place ain't free either.

LAD?
Rather than suggesting something that is defunkt by default, yes.
BTW, it would be interesting to get some real world feedback from
anyone who has this enabled already on a 32 bit platform.
This would most likely be enabled by default for anybody who has
installed a 32bit distro on a machine with 8GB memory.
