scary_leary:
try tightening an old stem inside...then use hammer too tap it out.

weston:
steel when rusty bonds like welding, try crush the seatpost in a vice & break out of the frame

selfpreservation:
try drilling a hole throught the diameter of the seatpost and inserting a metal bar and twist that , i have read posts on here avising filling the seatube with caustic soda (be fooking careful when doing this )cause you could damage the finish or yourself

MartyC:
You could try diesel, pour it along the edge of the frame where the seatpost goes in and around the slit in the frame and try giving the seat post a good whack with a big hammer to break the "join", I kid you not on this bit!  Whacking it with a hammer will usually break the join between the two metals as Weston says, the rust acts like a weld to a degree.
