Yes. They don't seem to capture colours. In a simple format (simple ==
2 bytes per character, 1 byte = character code, 1 byte = colour code).

True enough. I hasten to point out that I'm not trying to write something
for wide distribution (at the moment). This is just something to make
the FreeBSD Documentation a little more user friendly.
After poking a bit more through syscons.c, I think I should be able
to implement something like "press 'D' to dump the current screen to
/tmp/syscons.dump" or similar.
