If its your own message, then why can't you make it fit within the length of the box?
You could use multiple lines.

[edit]
Or, you could use this:

public class DriverStationLCDwWrap  {

    private static DriverStationLCD lcd = null;
    private static DriverStationLCDwWrap LCDw = null;//keep the singleton pattern going

    private DriverStationLCD.Line[] lcdLines =
    {DriverStationLCD.Line.kMain6, DriverStationLCD.Line.kUser2,
     DriverStationLCD.Line.kUser3, DriverStationLCD.Line.kUser4,
     DriverStationLCD.Line.kUser5, DriverStationLCD.Line.kUser6};

    private DriverStationLCDwWrap()
    {
        lcd = DriverStationLCD.getInstance();
    }

    public static DriverStationLCDwWrap getInstance()
    {
        if(LCDw == null)
            LCDw = new DriverStationLCDwWrap();
        return LCDw;
    }

    public void updateLCD()
    {
        lcd.updateLCD();
    }

    public void println(String text)
    {
        int length = text.length();
        int lines  = length / lcd.kLineLength;
        String blank = "                      "; // 21 spaces, clears the line.
        for(int i = 0; i < i < lcdLines.length; i++)
        {
            lcd.println(lcdLines[i], 1, blank); // Clear the all lines of previous text
        }

        for(int i = 0; i < (lines + 1) && i < lcdLines.length; i++)
        {
            int start = lcd.kLineLength*i;
            int end   = (start+lcd.kLineLength  >= length)? length : start+lcd.kLineLength;
            lcd.println(lcdLines[i], 1, text.substring(start, end));
        }
        updateLCD(); // call it since the the string has replaced the entire DS LCD buffer 
    }
}

(note, this is character wrapping. Your message can and will be chopped off to a new line)
For example: println("This is a very long message that will be split into several pieces");
becomes:
This is a very long m
essage that will be s
plit into several pie
