A good idea, but I found a fatal bug that if I display message in the  
first line in an empty
buffer, emacs will crash when I move backward. You can repeat it as  
following:
  1. load "tabkey2"
  2. open a new buffer or erase current buffer
  3. input (tabkey2-overlay-message "hello") and C-x C-e eval it, the  
message overlay
     will appear in front of cursor right after the parenthesis.
  4. C-b to move backward, then the emacs will crash.

I try it in emacs22 and emacs23, both have the same problem.
Anyway, I think make sure alway has a new line bellow is better, but
it will change the content of buffer.
