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.
