Just stumbled on Wikipedia's Portmanteau Category, and list of computer and technology puns. (Context. Was grabbing the link for Pajamahadeen.)

[Update:] Ed. points out that Homonymous portmanteaux have their own entry, too. Not to be confused with hominoid portmanteaux; though technically speaking that's what they are. (What's the term for words that sound like one thing but mean another?)
