Sorry that I cannot help but FYI I also got trouble with port-forwarding
with dropbear. I used it to Remote-Terminal to Win2K server and IIRC I could
go into the login screen but then things stopped. Switching back to SSHD and
everything worked. However it was about half a year ago and later versions
of dropbear may fix that.
