No, I don't think there is a workaround. TTDPatch can't give you extra stations, IIRC. You could try buying out computer players and destroying their stations. Remember also that buoys and oil rigs count towards the station limit - you may want to remove any extra buoys if you can.
good advice, buoys can easily be deleted, you don't need them that badly
as we all know TTD has some bit byte limits that can't be changed
i didn't know that depots counted too !
Well, back to work, lot's of it in the near future
