Interesting...
   Did you cover the case of hardware surfaces?  I was
under the impression that pixel access to a hardware
surface is expensive (although I could easily be wrong
:) ).  Of course, to a software surface it's going to
be way faster.
   Direct pixel access to an OpenGL buffer is
supposedly pretty slow, so for that the strings will
probably have to be cached.
