Reading the gentoo mailing list, it seems there's a fair few people who 
don't use initramfs. I get the impression they don't use initrd either, 
though.

I don't know too much about booting without an initramfs - I switched 
ages ago - so what is possible and what they're actually doing, I don't 
know.
