What do you mean exactly with bad areas?
Maybe you can send an image to show that.
Usually for polygons it is better to select a higher max-nodes and/or
overlap parameter in the tile splitter because this increases the
probability that the polygons are contained completely in the tile data.

I cannot say for sure but I would expect that using non rectangular
tiles is not really supported by mkgmap.
