Yup. ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test11/2.6.0-test11-mm1/broken-out/scale-min_free_kbytes.patch
Also, note that setup_per_zone_pages_min() plays games to ensure that the highmem zone's free pages limit is small: there's not a lot of point in keeping lots of highmem pages free.
