Hm I have used noweb in the past, but usually I run noweave on nw  files
noweave nonlinfd.nw > nonlinfd.tex
and then I latex on that file.

What is nolatex?

I think noweave should produce files with the extension .tex not
.nw.tex Hm I had to do 3 things:

 '(TeX-file-extensions (quote ("tex" "sty" "cls" "ltx" "texi" "texinfo"
 "dtx" "nw" "m")))

'(TeX-expand-list (quote
 ("%w" file "nw" t)
and finally 
 '(TeX-command-list (quote
("noweave" "noweave %w > %s.tex" TeX-run-command t t)

All via custom

I still don't understand you that should work since you can't run latex
on that buffer. So there is something I fail to understand.
