I seriously recommend to use Emacs' package manager for installation,
and NOT to overwrite files in Emacs' installation dir. Experience tells,
that this is always good for trouble in the long run.

Strange. I've reworked the Tramp patch a little bit. Function names have
changed, and more important, it has traces now. Could you please apply
this patch instead of the previous patch in tramp-integration.el? Rerun
your test with tramp-verbose set to 6, and send the Tramp debug buffer
if it still doesn't work as expected.
