The 'silent' option only works under 9.1.

The above quote was from the latest Quartus handbook, so it should work. Although perhaps you mean that the option does not work for the altsyncram components you are using. File a service request and complain.
While you are waiting for them to respond, create an altsyncram using the latest version of Quartus. Take a look at your old generated components and the new ones. Are they that different? If not, write a script that'll convert the components to the new style. Alternatively, work out the command-line requirements for qmegawiz to generate the components from scratch, eg., have a script read the old component file to parse out the important information and then call qmegawiz to create a new component.
