Are you sure you really updated /etc/ttys correctly?
  ttyu0   "/usr/libexec/getty std.115200"   dialup  on secure

What does 'ps ax | grep getty' say? Something like this:
   1416  u0  Is+    0:00.24 /usr/libexec/getty std.9600 ttyu0
or like this:
   1416  u0  Is+    0:00.24 /usr/libexec/getty std.115200 ttyu0

Then, check that std.115200 is indeed in /etc/gettytab.

Save for getty, I don't know what would reset the speed
to 9600... Maybe some weird setting in /etc/login.conf?
