    Subject[PATCH] Making keyboard/mouse drivers dependent on CONFIG_EMBEDDED

    I finally got sick of seeing bug reports from people who did not enable
    CONFIG_VT or forgot to enable the obscure options for the keyboard
    driver. This is especially a big problem for people who do make oldconfig
    with a 2.4 configuration, but seems to happen in general often.
    I also included the PS/2 mouse driver. It is small enough and a useful
    fallback on any PC.

    This patch wraps all this for i386/amd64 in CONFIG_EMBEDDED. If
    CONFIG_EMBEDDED is not defined they are not visible and always enabled.

    I only tried to give good defaults for PC type of hardware. So far
    the assumption is that people running other architectures know how
    to configure a kernel.

    I also included VGA_CONSOLE with this. Arguably a lot of people use
    fbcon now, but having vga console compiled in too as a fallback doesn't hurt.

    Hopefully this will fix one of the major FAQs on linux-kernel.
