Hi,
Certainly not *everything* but you could compile as modules some things
which otherwise you won't be able to use as modules (root fs etc.).
IIRC genkernel uses a 'default' config (equal to the one in LiveCD, if
not wrong). The whole idea is to load&mount "initramfs" in memory so to
have the required modules/lvm/raid things to start the real root-fs.
i'm using genkernel but just for the 'auto' initrd/initramfs thing,
otherwise using my custom kernel config with some 12-16 modules.
