Well, it's still useful to know how to prepare a development environment for the Reader (assuming some of us will eventually try to write custom applications). Besides, you may not be able to compile without first building the libraries and getting the include directories in place...
Did Sony supply a crosscompiler, or did you use the Crosstool, Scotty? At some point it might be nice just to make the entire develpment environement available for download and/or install.
IMHO, the info in the top post definitely belongs in the Sony Reader Hack Wiki.
