How about this:
In .logout:
	dirs > ~/.stack

In .login:
	if ( -r ~/.stack ) then
		foreach d ( `cat ~/.stack` )
			pushd $d > /dev/null
			pushd +1 > /dev/null
		end
		popd > /dev/null
	endif
	echo -n "Directories: " ; dirs

It works; I just finished testing it.  Note that this is NOT specific
to tcsh; it should work in almost any implementation of the c-shell
because this is all standard stuff.
