Hey, CCed Russell.

Btw. this shouldn't be true anymore. On the other hand, why do you need such a 
huge kernel?

It's not even possible to create kernel that big if you don't have some kind of 
initramfs in, right? Besides, you can use some kind of a compression, like LZMA 
or something to keep the size down.
