Putting

(when (and (boundp 'TeX-modes)
           (memq 'texinfo-mode TeX-modes))
  (TeX-modes-set 'TeX-modes TeX-modes t))

right after the `(require 'texinfo)' call into tex-info.el fixes the
problem for me.  However, I am not sure if this is the right fix or if
e.g. a simple `(defalias 'texinfo-mode 'TeX-texinfo-mode)' would
suffice.
