    With vesafb, you should be able to get any resultion you want at
    60Hz. Which is okay, because you have LCD.

    static int agp_intel_resume(struct pci_dev *pdev)
    struct agp_bridge_data *bridge = pci_get_drvdata(pdev);

    if (bridge->driver == &intel_generic_driver)
    else if (bridge->driver == &intel_845_driver)

    return 0;

    intel_agp tries to implement resume, try to put printk("something");
    mdelay(1000); in it and debug it this way.

    drivers/char/drm/i830_drv driver is apparently using DMA _and_ has no
    suspend/resume support. That looks dangerous to me, perhaps you'll
    need to implement those, too.
    When do you have a heart between your knees?
