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.
