From your comment I think I may have a misunderstanding about DirectInput - does it lock the mouse cursor position like DGA does? Or does it still allow the mouse cursor to move around, yet still report relative motion even if the mouse cursor is confined (by ClipCursor)?
Both, depending on cooperative level exclusive (mouse cursor hidden and doesn't move) or non-exclusive (mouse cursor behaves as usual). Some games mean to use exclusive mode but due to bugs end up acquiring mouse in non-exclusive mode (ex: quake, quake 2). On windows this is not a problem for full-screen games.
The DGA won't help - it covers exclusive mode only. And is currently disabled on most distros.
