No 2.4 still uses v4l not v4l2.  2.5 should have v4l2 (last I heard).

v4l2 supports deeper buffers for bttv and allow buffered capturing, so 
applications like mp1e don't drop buffers as much.  Application has to
handle having more than 2 buffers though (old bttv default).

v4l2 also seems to have a lower latency.
