I just brought my dead MacBook Pro to my AASP today and had a chance to chat with the tech about this situation. Normally they charge $50 for a diagnosis on out of warranty hardware but when he saw which machine I had he agreed to wave the fee no problem.
He said they are seeing tons of these 2.2/2.4 santa rosa MBPs coming in with dead boards, some that boot and some that don't. It's becoming their most popular in-for-repair model up there with the notorious iMac G5's with the bad capacitors. He fully agreed that it's not right that Apple is only covering the boot-able machines.
