Superpages can from a memory allocation angle be seen as a very strict form of page coloring - the problems are fairly closely related, I think (superpages are just a lot stricter, in that it's not enough to get "any page of color X", you have to get just the _right_ page). Doing superpages will automatically do coloring (while the reverse is obviously not true). And the way David did coloring a long time ago (if I remember his implementation correctly) was the same way you'd do superpages: just do higher order allocations.
