The kernel cannot be 'built' at boot time persay, but the modules to
load can. For a cd that will run just about anywhere, I'd recommend
grabbing on of the releng release kernel configs from cvs
(gentoo/src/releng/kconfig/2005.0/x86) and using that. It has the
important stuff enabled, and nearly everything else as a module. Since
it is being built through genkernel, you also end up with an initrd that
will handle a lot of hardware detection. 

As for how to specify the config, it will be located somewhere outside
the chroot, and should be listed with a fully qualified path.

Note that if you plan to use precisely that config, you should first
place it in a kernel source tree for the actual kernel that will be used
and do a 'make oldconfig'. genkernel will do this for you, but for input
it uses /bin/yes, which may not be desired.
