Both when polling the current turbo status (in poll_turbo_status mode)
and when handling thermal events (in ips_irq_handler) the current status
of GPU turbo is updated to match the hardware status. However if during
driver initialisation we were unable aquire linkage to the i915 driver
enabling GPU turbo will lead to an oops on the first attempt to determine
GPU busy status.
Ensure that we do not enable GPU turbo unless we have driver linkage.

Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config -
I don't know. But it has silently been there until I tried 2.6.36-rc2,
where it broke the build because I don't have LED support turned on.
Attached patch fixes things up.
(I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise
I get unsightly core dumps out of scripts/kconfig/conf).

The Linux ACPI core locates the ACPI video devices for us and marks them
with ACPI_VIDEO_HID. Use that information to locate the video device
instead of a half-baked hunt for _BCL.
This uncouples the detection of the number of backlight brightness
levels on ThinkPads from the ACPI paths in vid_handle.
With this change, the driver should be able to always detect whether the
ThinkPad uses a 8-level or 16-level brightness scale even on newer
models for which the vid_handle paths have not been updated yet.
It will skip deactivated devices in the ACPI device tree, which is a
change in behaviour.
