Those are just two different ways for setting up a splash screen; I think gentoo is currently more directed to bootsplash rather than fbsplash. But neither of them is mandatory for framebuffer usage (and framebuffer console). In order to use the framebuffer, you just need to load the relevant module and use fbset or compile the driver into the kernel and pass the right "video=..." paramenter to the kernel and you're set.
Are you sure Gentoo is more directed to bootsplash. I think bootsplash is discontinued and fbsplash has taken over it, as mentioned at the bootsplash wiki.
