According to the help file for Racial edges, svirfnebli are supposed to have access to resist toxins edge, and loremaster edge. However, when I discuss guild prereq resist toxins, it tells me there is no resist toxins edge. When I discuss guild prereq loremaster, it tells me I will never be able to learn loremaster.
