Although I'd err on the side of caution, is that definitely knackered given that the crack is above all the welds? Other than the issue of keeping the seatpost at the correct height, what would happen if you just used a super-long seatpost that went into the frame well below the junction of the top tube, seat tube and seat stays? Incidentally, how long is that seat post?
