As it was already said in this thread, passenger module
unconditionally set buffer size and it's not configurable. There
should be something like "passenger_buffer_size" directive, but
it doesn't exists.

Either bug passenger module authors or use another module to talk
to backends (e.g. standard fastcgi or proxy).
