In 2.6.32 (Lucid) there's an /sys/devices/virtual/backlight/acpi_video0 interface for Aspire 5742Z, and brightness hotkeys do modify the values of the files in that dir, but the actual laptop brightness isn't changed.
In 3.0.0-9 (Oneiric beta 1) there's no /sys/devices/virtual/backlight interface at all.
If I boot with acpi=off, the brightness keys correctly modify brightness, but of course I lose all other ACPI functionality.
I tried some of the other acpi-related kernel parameters (acpi_backlight=vendor etc) mentioned in
* https://wiki.ubuntu.com/Kernel/Debugging/Backlight
* https://wiki.ubuntu.com/DebuggingACPI
* www.kernel.org/doc/Documentation/kernel-parameters.txt
* http://www.lesswatts.org/projects/acpi/debug.php
to no avail, brightness only works with acpi=off or acpi=ht.
I tried the fwts tool for ACPI testing, and it produced some errors, I'm attaching the output.
I also tried playing with acpiexec, but calling the _BCM method didn't change the brightness either.
`ubuntu-bug linux` doesn't work from the oneiric beta live CD, I'll manually attach lspci etc as well. |

WORKAROUND: echo 123 > /sys/class/backlight/intel_backlight/brightness
WORKAROUND: If I boot with `acpi_osi=Linux` in the kernel command line, I can change the brightness, but the brightness window doesn't pop up.
