It pops up about once a year, everyone agrees it'd be a good idea,
and then nothing happens. Last year, I started picking over
Terrence Ripperda's original implementation, but that needs a bit
of work. (http://lkml.org/lkml/2005/5/12/187)
Whoa, two years even. Time flies.

Ah.
This might explain why nothing happens :).
I had something much simpler in mind.
Just the basic PAT setup and some new pgprot_ types which affected
drivers could use directly.
Like in(drivers/char/drm/drm_vm.c) where ia64 has a
pgprot_writecombine() function.
