Disable Map Generation

[Der_IVIaulwurf]

hello,
i'm running a server on my raspberry pi with a pre-generated minecraft-singleplayer map. everything works fine, but when i reach the end of the prerendered map, and new land is generated, it doesnt fit into the old world. for example iceland is generated in the middle of a desert biome...

is there any way to completely disable world generation?

i would then generate the world manually as big as i need, and then only load it up to the server, so there wont be generated non-fitting chunks.

I also want that, but MCServer doesnt support non-existing chunks (bukkit does).
But its posible to make a plugin that generates all new chunks air. I'll probably make it because I also need it.

There should be an air generator by default, and if not there should be one.
