Despite a potential shareholder revolt, Yahoo! is taking bids from investors for a 19.9 percent stake in the Sunnyvale, Calif., company.

The deadline for the bids, set by Yahoo!’s bankers Goldman Sachs and Allen & Co., was yesterday, and the less than 20 percent offering means the deal won’t face a shareholder vote.

Silver Lake Partners and TPG are among the private-equity firms to slip in offers. Microsoft and Silicon Valley heavyweight Marc Andreesen are teaming up with Silver Lake on the bid as a consortium, a source with said yesterday.

TPG may deliver an offer at a higher valuation on Yahoo!, whose market cap is about $19 billion, but the Silver Lake consortium comes with the promise of Andreesen’s star power and tech bona fides to help turn the company around, the source said.
