My aluminium seat post is seized into my carbon frame. To make matters worse the seat post is snapped at the seat post collar - nasty crash.
Anyone have a way to get it out? Or is it time for the dump?

What you need is some way to grip or gain purchase on the post so you can apply a force to, then apply the usual methods to free the post from the frame.
Possible means of gripping the post I can think of:
GCN has a video showing how to use hot water to free up the post. It seems that a substantial amount of force is still needed to pull the post out though.
