Mod_tile does have projection baked-in:
        https://github.com/openstreetmap/mod_tile/blob/master/renderd.py#L163

You may find it necessary to play with the scale of your projection so that the 
units of spherical mercator (equatorial meters) approximately match yours. For 
example, an Albers projection with a standard parallel in the continental 
United States would be scaled up a bit to get the numbers to match.
