The attached patch allows the cairo generated %%BoundingBox and 
%%PageBoundingBox comments to be overridden using the
cairo_ps_surface_dsc_comment() API.

eg

surface = cairo_ps_surface_create()
cairo_ps_surface_dsc_comment(surface, %%BoundingBox: 100 100 200 200");
cairo_ps_dsc_begin_page(surface);
cairo_ps_surface_dsc_comment(surface, %%PageBoundingBox: 100 100 200 200");

Please test to see if this meets your requirements.
