Even stutterwarp can do it, with effort.

Get above a gravitating body.  Not orbiting, just falling.  Use the stutterwarp to maintain altitude (average altitude is fine, we're not fussy).  As you continually fall in the same direction towards the body, you build up real momentum.  Achieve whatever velocity you want, then warp away and line the velocity vector up with the target planet.  Boom.  (Preferably, sometime before 'boom', you get off the thing…)

 Shutterwarp or some other kind of inertia/momentumless drive, and some kind of contra-grav that doesn't let you just lift something to orbital height and drop it would seem to be required. Otherwise known as 'magic'.

Ground-based wormholes or other planet to planet teleportation (also powered by magic, of course) is another way round it, though if you want spaceships in your game, they kind of miss the point.
