Are you sure Chris because I wrote an AD query tool using PHP and I can query for cn=%computername% and it returns a lastlogontimestamp....

Query for a computer account:
Code:

            [lastlogontimestamp] => Array
                (
                    [count] => 1
                    [0] => 127608227380157206
                )

            [35] => lastlogontimestamp
