Right, I have:
Section "Device"
Option "Backlight" "intel_backlight"
Identifier "Card0"
Driver "intel"
BusID "PCI:0:2:0"
EndSection
in there currently.

Nope.
Kernel command line is like this:
[ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.11.0-rc3+ root=/dev/sdb2 ro root=/dev/sdb2 ignore_loglevel log_buf_len=10M resume=/dev/sdb1 acpi_backlight=vendor video.brightness_switch_enabled=0 i915.i915_enable_rc6=4 i915.i915_enable_fbc=1 i915.lvds_downclock=1 i915.powersave=1
and acpi_backlight=vendor doesn't make any difference. It still works
over sysfs though.
Thanks.
