This sucks due to the fact that we page in 4k blocks and most of the 
items that people are wringing their hands about are << 4K.  It's even 
worse in that we often use a 4M page to back the kernel.

It sounds like a neat idea, but basically it's just not worth the effort. 
There are better things to spend your time worrying about.  8)
