/proc is guaranteed to be mounted in D-I.

For 2.6.29 and 2.6.30 you can't depend on it being mounted. See usb-kbd.c
in kbd-chooser; again the code is fairly simple (I hacked on it ages ago
so it must be as I knew even less C then than I know now).
But note that /proc/bus/usb (or rather usbfs) is going away in 2.6.31! See
#534412, it's very relevant.

Maybe you can just use /proc/input/devices (which _will_ be available) as
I don't think the distinction between USB and PS/2 is really relevant
anymore?

No. 2.4 is dead for Debian. You really only need to worry about Squeeze
and that is 2.6.31+.

Not our problem. If the user installs without keyboard, it's up to him to
configure userland for it. Just as he may have to install software for
other hardware that is added after the installation.
D-I's job is to install the system as we find it, which means that there
is no reason to install c-s onto a headless system.
