Since I built emacs-w3m from cvs, would it be possible that I need to
turn on a particular option or include a certain library to enable
emacs-w3m native ftp support?

When I executed this code (w3m-use-ange-ftp nil, no ange-ftp
customisation), the root directory of the server was displayed
correctly and I heard the beep as described before. Once I wanted to
enter one of the subdirectories, the debug buffer popped up and showed
the following:
----*Backtrace*----
Debugger entered--Lisp error: (ftp-error "FTP Error: DIR failed: 425 Can't build data connection: Connection refused.")
  signal(ftp-error ("FTP Error: DIR failed: 425 Can't build data connection: Connection refused."))

Apparently, that's precisely the case.
