I like to be able to resize maximized windows, but when I went to set the effect in (up-to-date) Mageia, it appeared to have been removed. However, it turns out that the text for that option is now incorrect--the option I want is actually still in the same place in the System Settings menus, it simply appears to be gone.
System Settings > Window Behavior > Window Behavior > Moving
Under Windows group, the fourth option now says: Display borders on maximized windows
However, what it is supposed to say is: Allow moving and resizing of maximized windows
That is what is says in Mandriva 2010.2, and that is what it is actually still doing (setting kwinrc to include/not MoveResizeMaximizedWindows=true).
