I have found using cramfs helps quite a lot in low memory
situations, but the penalty you pay is the filesystem itself
(i.e. the stuff you store on the boot media) is larger. So
its a tradeoff between runtime memory use (cramfs is very
good) and boot media storage space (cramfs is less compact
than a gzipped ext2 fs). I expect a similar thing applies
