yes inline code tends to get mangled. Ive converted gdal2tiles.py to html and 
code attached but it bounced due to size restriction. Code is available at 

http://chrish.selfip.com/gdal2tiles/


Apparently its going to be included in the next release of 
gdal. maptiler is just the gui in wx by the same author.

If you have the time/interest, pls consider having a look at the code. From 
your notes I understand the problem but as the code is well commented with 
inline tutorial, I think I may have referred you to the wrong section. 

A final thought. Since the issues you describe can be potentially circumvented 
my means of a real WMS and that is getting a bit easier to work with at this 
end, would it be possible then to produce standard sized tiles for standard 
map integration and then call the needed tile size for gpsdrive via gdal 
itself or alternatively another script included with gpsdrive. 

This would also allow for easier maintenance and updating of rasters which are 
released on a quarterly basis by NOAA.  

Thanks for your help and interest.
