    sysdev-buildroot: disable section about testing on IGEPv2 with HDMI output
    
    This HDMI output has been tested by participant of my training
    sessions twice, and it hasn't worked, despite many tries. It has also
    never been tested with IGEPv2 rev6 with recent kernel versions. Until
    this is seriously tested, let's disable it, because it is very
    annoying to have invalid instructions.

-\section{Tests on the IGEPv2 board}
-
-If you have graphical displays to connect your IGEPv2 board to (LCD
-display with DVI-D or HDMI input, TI Pico Projector...), and the
-corresponding cables (HDMI to DVI-D or HDMI to HDMI), you can test
-your root filesystem on the board.
-
-You can skip to the next section if you don't have a display.
-
-Here's what you can do:
-
-\begin{itemize}
-\item Edit \code{etc/inittab}, uncomment the line with \code{ttyS0}
-  and replace all the occurrences of \code{ttyS0} by \code{ttyO2}
-\item Either copy the ext2 image to a block device that can be
-  accessed by your hardware (flash card reader, USB drive...)
-\item Or mount the ext2 image and copy its contents to a flash
-  partition on your board.
-\item Connect your board to an DVI-D or HDMI display
-\item Get the latest Linux 2.6.39.x sources, take the default
-  configuration of OMAP2 and build this Linux kernel with the
-  following settings:
-\begin{verbatim}
-CONFIG_OMAP2_DSS=y
-FB_OMAP2=y
-CONFIG_PANEL_GENERIC_DPI=y
-LOGO=y (optional)
-\end{verbatim}
-\item Add the following settings to the boot arguments:
-  \begin{itemize}
-  \item \code{console=tty0}\\(allows you to have both a framebuffer
-    and serial console)
-  \item \code{vram=12M}\\(video RAM)
-  \item \code{omapfb.mode=dvi:640x480MR-16 at 60}\\(example for the
-    Pico Projector. You may first try to do without this parameter,
-    and then specify a mode that your monitor supports).

-    Display SubSystem driver)

+% =================================================================
+% The following section is commented out, because the HDMI/DVI-D
+% output didn't work in various tests, and hasn't been tested on
+% IGEPv2 rev6 with recent kernel versions. Until this has been tested,
+% we shouldn't advertise instructions that simply don't work.
