Ok, how about this: completely suspending all I/O can be done. two possible answer: 1. suspension on root device: reboot using a LiveCD, and mount the rootfs as readonly. 2. suspension on non-root device: unmount it first - after removing all dependencies, remount as readonly. now your device will suspend all write but not read.
