Hang on, shouldn't the loader be handling this for you ?  Ie shouldn't 
the loader decide if it is appropriate to map a particular section to 
this fast area of on-chip RAM and if so handle the relocating of the 
section to that address ?  (Maybe the program can give the loader a hint 
that a particular section would like to be placed in on-chip RAM, but it 
is up to the loader to decide how this precious resource should be 
allocated).

Nope, sorry.
