I'm not sure I understand what you mean by "the corresponding expression
doesn't map to termcap". Do you mean that FreeBSD's curses library need
to be patched to handle 256 colors ? (using 8.1 RELEASE here; ncurses is
version 5.7.20081102).

However, both Co and pa are documented in termcap(5) as being the number
of colors and bg/fg pairs. In addition, I added the following to my
termcap file :

rxvt-unicode-256color|rxvt-unicode terminal with 256 colors (X Window System):\
        :cc:Co#256:pa#32767:tc=rxvt-unicode:

When running [1], I do get 256 colors. However, tmux is in black & white
(actually, it already was, unless run with something like
TERM=xterm-16color tmux new ; but we don't want to lie about $TERM, do
we?).
