The TextRenderer.DrawText always uses the TranslateTransform (it shouldn't do it unless you give it the option TextFormatFlags.PreserveGraphicsTranslateTransform)

Small example included. On Windows you'll get on two lines AA and BB (AA\nBB), on Mono you'll get everything on the same line overlapped (BB "over" AA)

namespace WindowsFormsApplication8
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }

    public class Form1 : Form
    {
        public Form1()
        {
            this.Paint += this.Form1_Paint;
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.TranslateTransform(0, 10);

            TextRenderer.DrawText(e.Graphics, "AA", this.Font, new Point(0, 0), Color.Black);
            TextRenderer.DrawText(e.Graphics, "BB", this.Font, new Point(0, 0), Color.Black, TextFormatFlags.PreserveGraphicsTranslateTransform);
        }
    }
}
