I have Compaq Deskpro EN systems all with 133Mhz RAM. They have the vertical lines at any resolution higher than 1024x768.
However, contrary to what has been described in an above post, it is NOT some Intel weirdness. I know this because I'm running Windows XP on identical hardware at 1280x1024 (at 75Hz) and it is fine. Therefore it is a problem with Linux/Xorg.
