This really isn’t as much a bailout of the suppliers as it is a bailout of the Big Three who didn’t pay for the actual parts provided by said suppliers:

The administration will create a financial entity to provide money for auto parts that large suppliers have shipped to the Big Three automakers but have not yet been paid for. In a statement, Treasury Secretary Timothy Geithner said the “Supplier Support Program” would “help stabilize a critical component of the American auto industry during the difficult period of restructuring that lies ahead.”
“The program will provide supply companies with much needed access to liquidity to assist them in meeting payrolls and covering their expenses, while giving the domestic auto companies reliable access to the parts they need,” Geithner said.
Auto suppliers have sought up to $25 billion to stabilize the beleaguered U.S. auto industry and have met with members of Obama’s auto industry task force, which is reviewing $17.4 billion in loans to General Motors Corp. and Chrysler LLC and requests for billions more.
The program will be run through U.S. automakers — General Motors, Chrysler and Ford Motor Co. — that agree to participate. Suppliers to those companies would have to agree to terms of the government-backed protection and pay a small fee for the right to participate.

And the suppliers have to pay a fee for this? I don’t remember any of the counterparties who were “stabilized” by the AIG bailout having to pay for the priviledge of being made whole on their contracts. Also, what are the government’s terms? (Hmm, any green strings attached?) Again, no such terms for the bailed-out AIG counterparties.
