I know when Vault Disney was running the episode in the late 90s, it just spliced out the offending parts.
I have no idea if there's any truth to the rumors that the Disney Channel unwittingly ran the uncut version in the early/mid 80s. They certainly made fewer cuts to their cartoons than they would in the 90s, but they still cut out racial stereotypes (the Donald Duck short "Spare the Rod" was only ever seen in a heavily abridged version at the end of one episode of "Donald Duck Presents," that removed the entire section where Huey, Dewey and Louie disguised themselves as pygmies).
