"Yes", from Emacs 21 to 22,
there was the "big change" from  Ange-FTP to Tramp.
When using some emacs-22 *pre*-releases, tramp did not work *at all*
for me, and that had even be a princpal reason why I had given
up using "emacs 22 alpha" at all.  
With the release (Emacs 22.1), I've found that "they" must have
fixed the most blatant tramp problems, because now I could use
it.  Still, I found it to differ a bit from previous ange-ftp...

you have

    gj> "c:/windows/ftp.exe"))          ;; 95/98/ME

I would assume that 'ange-ftp....' settings are no longer
relevant in Emacs 22 at all, since ange-ftp has been replaced
with tramp.

So I think you should look for solutions setting
tramp-<foo>-<bar> variables rather than ange-ftp ones
