And I can confirm that it can work well on the kernel of 2.6.29. In my test the video and i915 are compiled as modules and the KMS mode is disabled. a. If only video driver is loaded, no ACPI backlight I/F is registered and it is not bound with the ACPI video device. In such case there is no oops when the video driver is unloaded. b. If the video/i915 driver is loaded, the ACPI backlight I/F is registered. The I915 driver is unloaded and then the oops appears when the video driver is unloaded. After checking the source code it seems that the function of acpi_video_exit is called when unloading the i915 driver. Then the acpi_video_exit is called again when unloading the video driver.
