I was not able to find documentation for procedure arity inspection for 
Chez or Scheme 48.  Please let me know if you have pointers.

I was able to find these:

http://www.gnu.org/software/mit-scheme/documentation/mit-scheme-ref/Arity.html
http://docs.plt-scheme.org/reference/procedures.html

I'm interested in any other relevant links.

Thanks,
