Sure. And thanks!

I applied the patch and byte-compiled tramp.el. Looks like I did it right:

[root@localhost site-lisp]# diff tramp.el tramp.el.orig
5855,5856c5855,5859
<     (when (not (tramp-get-connection-property proc "check-remote-echo" 
nil))
<       ;; No echo to be handled, now we can look for the regexp.

[root@localhost site-lisp]# ls -l tramp.el*
-rw-r--r-- 1 root root 303964 2009-03-17 23:19 tramp.el
-rw-r--r-- 1 root root 285934 2009-03-17 23:20 tramp.elc
-rw-r--r-- 1 root root 304070 2009-03-08 17:37 tramp.el.orig

I then started a fresh emacs and did the double attempt to connect as 
root. To me it looked just like last time but I've uploaded the debug 
buffer anyway: http://www.solarphysics.kva.se/~mats/debug3.txt
