Calling Motorola's ( MOT ) board complacent, billionaire investor Carl Icahn turned up the pressure to get a director seat. In a letter to Motorola's executive directors Friday, Icahn changed his message a bit, saying stock buybacks and dividends should take a back seat to fixing operational problems. Icahn says he and his affiliated investment groups have accumulated 68 million shares, a 2.8% stake in Motorola, in a bid to influence the company's decisions. Previously, Icahn had targeted Motorola's lackluster stock performance and huge cash pile as an opportunity for shareholders to benefit from a possible stock repurchase or a massive dividend. Now, after Motorola's abysmal four-quarter financial-disappointment streak, Icahn says the company's deteriorating business needs immediate help. "My experience tells me that Motorola's problems reflect not only operational failures but are also symptoms of a passive and reactive board," Icahn says in his letter.
