Well, I guess that I forgot to run that through mhbuild.

How large is your display?  Mine is at 1280x1024 and I can't
seem to reproduce this one.

Okay, I see this one too.  I have looked a bit and it would
be pretty trivial to hack the Xserver to put the cmap back into
a sane state, but I've been thinking that perhaps the kernel
should do this one when the Xserver exits so that we don't have
to rely on the Xserver playing nice (or not getting -9ed.)
Opinions?

Anyway, attached please find a tiny program that I just wrote
which works:

cmap [-f tty] [-x] idx rval:gval:bval

and it opens tty and sets the colourmap entry idx to rval:gval:bval.
If you set:

cmap 0 0:0:0
cmap 1 255:255:255

You should get back to something useful.  If that doesn't quite work,
try:

cmap 0 0:0:0
for i in $(jot 255); do
   cmap $i 255:255:255
done

Remember that there is a point in there where you'll have white on
white.  You can avoid that by experimenting with 255:0:0 to get things
right.
