By "alternate" do you mean:

# Local Variables:
# stuff
# End:

vs.

-*-stuff-*-

?

If so, this isn't working for me either (I get "malformed modeline"):

-*- org-babel-default-header-args:R: ((:session . "foo")) -*-

I read through the *info* on local file variables and both of the
above seem like they should be correct. Wouldn't it be the colon?
Emacs is looking for VAR:VALUE. Here's from files.el, which contains
the function =hack-local-variables=. While not an elisper, this looks
like it wouldn't figure out two colons:

		  (while (and (not (eobp))
			      (or (not mode-only)
				  (not result)))
		    ;; Find the variable name; strip whitespace.
		    (skip-chars-forward " \t")
		    (setq beg (point))
		    (skip-chars-forward "^:\n")
		    (if (eolp) (error "Missing colon in local variables entry"))
		    (skip-chars-backward " \t")

Isn't this sort of saying, "split up the var:value pair by starting at
line beginning, going to the first =:=, and then looking for a
newline? If so, I'd take the execution as trying to set:

=org-babel-default-header-args= to a value of =R: ((:session . "foo"))=
