Hi,

if I use the new mobo with the default vertical frequency 60 Hz, e.g.
when booting an Ubuntu flavour live DVD or at the bootloader menu,
there's an annoying flashing line in the upper left corner of the CRT
monitor, what ever settings I'm using for the monitor, e.g. even if I
zoom in at max. The flashing isn't noticeable for 1152x864 at 90 Hz. I
still need to test if it's possible to select a higher vertical
frequency without an xorg.conf, but I doubt that xrandr will allow
other frequencies without xorg.conf.

I sometimes need an old Ubuntu Quantal and booting it does end with a
black screen. If I boot with "nomodeset" I don't get a black screen,
but then it suffers from the 60 Hz issue.

$ grep LABEL\ Light -A4 syslinux.cfg
LABEL Light
    MENU LABEL Ubuntu ^Q LightScribe Rt
    LINUX /.boot/ubuntu_q/boot/vmlinuz-3.6.5-rt14
    APPEND root=LABEL=q ro nomodeset
    INITRD /.boot/ubuntu_q/boot/initrd.img-3.6.5-rt14

Is this a known issue for Intel HD Graphics?

I've never experienced this before, when using NVIDIA and ATI graphics.
