I'm not sure how much space we need, but since speed is not an issue [we want a kernel we can install with, not one to keep] adding '-malign-loops=0 -malign-jumps=0 -malign-functions=0' will shrink things a bit (by removing all instruction alignment padding). Additionally, -fomit-frame-pointer will save a couple of bytes per function (and there are a lot of functions in the kernel). Some of the other `-f' options should reduce code size, but I'm not sure which ones are safe in gcc 2.7.2.1. These will also come in handy when it becomes necessary to shrink boot2 those few essential bytes...
