The user space helper would use Int10 VBIOS calls to list and set the modes. I haven't worked with these chips, so this is just based off from what has been posted to dri-devel. Is this why we don't have fbdev drivers for these chips? -- Jon Smirl jonsmirl@gmail.com ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
