AutoCAD 2008 has a new Mtext feature to allow the creation and editing of multiple Mtext columns.
Files required for this exercise:
Floor_Plan.dwg
General Notes.doc
Create an MTEXT object in the lower right box of the drawing.
Copy and paste the text from the ”General Notes.doc” file to the MTEXT object.
Locate the Columns button in the Text Formatting toolbar (In-Place Editor) and select Dynamic Columns mode>manual height. 
Click OK on the Mtext toolbar.
Change the text into two columns utilizing the grip at the bottom-center of the MTEXT object.
And there you have it, Multiple Text Columns now in AutoCAD.
Completed DWG with Multiple Column Mtext
