Are you referring to boot-time allocations using get_free_pages() instead of bootmem? Killing those off would be nice, yes. It limits the size of some hash tables on larger machines where "proportional to memory" means "bigger than MAX_ORDER". (Changing the algorithms to not use gargantuan hash tables might also be an interesting exercise but one I've not got the bandwidth to take on.)
