I don't think it is related. I don't have problems switching the outputs (frankly, didn't try) and I do have problems restoring backlight, very similar to what I had earlier in 2.6.37.
Right, but it affects the registration of the backlight and ACPI video interface as well, so can affect backlight restore on resume. In my case, without the above patch my backlight wouldn't be restored on resume, so I'd have to manually echo a value into /sys/class/backlight/<foo> to get my display back.
Ok, I tried, but only to find out that my tree already has the patch (it is in mainline since today). So it definitely does not help.
Thanks anyway
