v.overlay is much more powerful, perhaps it can help.
maybe you could select areas touching polygon boundary features and then
v.overlay "not" them away from the culled version you already have.

note it will only work on features with cat numbers, so you'll have to give boundaries can numbs with v.category first. usually they don't have them.
