Use "sliding" bitmaps - that is how I did it. You put the text on one, the
background it is to be animated over in another, with a third "master"
bitmap holding the background. Then

1) Draw the text on the temporary text bitmap.
2) Blit this to the slider bitmap.
2) Blit slider to screen in a certain x position, increment the x when done
to get movement.
3) Erase the slider bitmap from the master bitmap
4) Repeat from 2

If you do not catch it mail me - I have working code that does exactly
this.
