Interestingly, that is gone since 2.6.37.
A diff of the dmesg between 37 and 38-rc1 (+up to git 8d99641f6c1a)
shows (besides other things):
(no idea if that is important)
-Switching to clocksource tsc
+Switching to clocksource hpet
and here it is:
-acpi device:01: registered as cooling_device2
-input: Video Bus as /devices/LNXSYSTM:00/device:00/PNP0A08:00/LNXVIDEO:00/input/input2
-ACPI: Video Device [OVGA] (multi-head: yes rom: no post: no)
+No ACPI video bus found
(also the cooling_device2 is gone)
Interestingly, adjustment via sony-laptop does work, but only
at first boot, not after suspend?!?!
