$ modprobe viafb mode=720x576 bpp=32 refresh=50 TVon=1 TVoverscan=1

It ssems that you have a VGA frame-buffer driver loaded... Try to boot
without frame-buffer at all (and without fbcon), then only load the
viafb driver.
Maybe your viafb driver if /dev/fb1 instead of /dev/fb0 and just work
as-is, the color stripes being just memory interferences between the two
drivers. Try dfbshow to really initialize the video RAM.
