It works on my system:
mount -o remount,ro /usr
cd /usr
touch test
touch: cannot touch `test': Read-only file system

Best is to change this in /etc/fstab and then add this to /etc/apt/apt.conf
  DPkg {
           // Auto re-mounting of a readonly /usr
        Pre-Invoke {"mount -o remount,rw /usr";};
        Post-Invoke {"mount -o remount,ro /usr";};
  }

Apparently this doesn't always work:
