Mixing antifreeze with your oil is worse than dumping it in a hole, because now you've messed up the whole drum of waste oil.
+1 The approved disposal method for coolant is to flush it down a sanitary sewer (toilet) connected to a municipal sewage treatment plant. If you have a septic system, very small amounts spread over days can be flushed, but not too much at one time, or you can disrupt the organic balance of the system.

This is what I do with my used coolant too.
I was told by a guy that owns a company that manufactures water testing reagents for HP. He told me the only reason that coolant is considered hazardous waste is because the coolant is in contact with the solder in radiators and someone got the idea that this contact leaches lead into the coolant.
I also read something similar, but I don't recall if the article was sympathetic or contrary to the above statement.
