Looking through the Compiz code, Compiz *should* be respecting the hints. It takes the hint that GTK+ has and removes the action:
http://git.compiz.org/compiz/core/tree/src/window.cpp#n667 This is then set to the _NET_WM_ALLOWED_ACTIONS property on the window, which the decorator (which I believe is unity-window-decorator in the version of Ubuntu you have) then picks up (through libwnck) and paints the minimize button on the frame. Can you check with xprop what the value of _NET_WM_ALLOWED_ACTIONS is on the window?
