If I understand correctly, what you want is the same as conditional advertisements: http://www.cisco.com/en/US/tech/tk365/tk80/technologies_configuration_exampl... except that it needs to be applied to received routes instead of advertised routes. In other words, it's not enough for you to dump the bogon traffic in a blackhole; you also want to dump bogonish routes received from your peers before they even get to your RIB. If I understood it right, a naïve look at it would be that since the function already exists in the other direction it should not be too big of a deal to do it the other way, but I'm not the one compiling IOS.
