    sh-3.2$ grep -i VIDEO .config
    CONFIG_ACPI_VIDEO=y

    ...so I think it is ACPI video.

    sh-3.2$ grep -i THINK .config
    CONFIG_THINKPAD_ACPI=y
    # CONFIG_THINKPAD_ACPI_DEBUGFACILITIES is not set
    # CONFIG_THINKPAD_ACPI_DEBUG is not set
    CONFIG_THINKPAD_ACPI_UNSAFE_LEDS=y
    CONFIG_THINKPAD_ACPI_BAY=y
    CONFIG_THINKPAD_ACPI_VIDEO=y
    # CONFIG_THINKPAD_ACPI_HOTKEY_POLL is not set
    sh-3.2$

    ...and yes, I think it only happens on reboot.
