I have a long title for my beamer presentation and ue the \titlepage{} command. The title is automatically split over 4 lines. As I am using a tall font (arev), these lines are squashed together. I can use something like \newline \vskipt6pt where the line breaks occur to get roughly what I want (using \\ seems to insert a spurious comma). I am using the contributed Torino theme.
This there a way to `automatically' increase this spacing for the title only?

Here's a possible solution; the idea is to redefine \insertsectionnavigation and \insertsubsectionnavigation (implemented in beamerbasenavigation.sty) to use a two-column layout produced using the multicols environment from the multicol package; a redefinition of the headline template is also needed to reduce the height of the headline with this new layout:

An image of the headline of one the frames, showing the sections and subsections with the requested two-column layout:
and just for comparison, the same headline using the default Warsaw theme:
Change \providecommand\insertframetitle{} to \providecommand\insertframetitle*{}.
From the beamer user guide:
If you add one star, three things happen. First, the template is put inside a TEX-group, thereby limiting most side effects of commands used inside the template. Second, inside this group the beamer-color named element name is used and the foreground color is selected. Third, the beamer-font element name is also used. This one-starred version is usually the best version to use.
Edit: Thanks to Ignasis comment, I was able to figure it out. Use struts and change the alignment of the content in the parbox.
\providecommand\insertframetitle*{}
\setbeamertemplate{headline}{
\hspace{1cm}
\fbox{\parbox[][1.1cm][b]{.65\textwidth}{\flushleft\bf\Large\strut\insertframetitle\strut}}
\begin{textblock*}{100mm}(.8\textwidth,-1.0cm)
\includegraphics[width=2.0cm]{logo.pdf}
\end{textblock*}
\vspace*{0.2cm}
\hspace*{0.6cm}
\tikz \fill [] (0,0) rectangle (9.0, 2pt);
}
\strut is similar to doing \vphantom{}. I looked up the default definition of the frametitle (in beameroutertheme.sty) and found that it contained \strut\insertframetitle\strut. This together with changing from \parbox[][1.1cm][c]... to \parbox[][1.1cm][b]... gives you exactly what you want!

You can use
\fontsizeto control the font size (first argument) and the value of\baselineskip(second argument); usually, the value for the second argument is aprox. 20% more than the first argument, but you can use the value that best suits your needs:
