Some time ago I wrote a quick and dirty design for a zone allocator. I guess now is the time to dust off the design (http://www.nl.linux.org/~riel/zone-alloc.html) and think up a good allocator for 2.3 and beyond.
The discussion should probably be held on the Linux-MM mailing list. Linux-MM@kvack.org can be subscribed to by sending a message to majordomo@kvack.org...
