What’s another $40 million to a billionaire? Hong Kong’s Li Ka-shing, chairman of telecom giant Hutchison Whampoa, revealed during a conference call that he has raised his stake in Facebook by another $40 million or more. This is on top of the $60 million he previously invested.

That brings his total personal investment in the U.S. social networking site to at least $100 million. No word on whether Facebook’s $15 billion valuation has changed from when Ka-shing first joined Microsoft in putting money into the company. We’re guessing not.
