Sorry, I find it not so clear too...
- You want framebuffer support so you run the configure step
enabling the options I mentioned above, as built-in
(there are 2 ways to add a feature in the kernel, built-in
and module)
- Because the framebuffer feature is enabled as built-in into
the kernel, the kernel will be recompiled so you have to
install the kernel image after the compilation
(cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.11 or
/boot/vmlinuz, up to you)
- there is a way to enable framebuffer as module and make
an initrd to load it at boot, but I never tested that
