The second screen works fine with the attached patch. It actually is 6 months old but seems to have been lost in the wild...
You don't have the problem of the second backlight still off? On our Iconia, we need to trigger a special DMI command to set it up (SDSS, IIRC).
No, with the patch, it worked out-of-the-box.
mmm, this is weird. We must not have the same bios or device version. We need to explicitly set the LCD2 up.
I can even control the brightness in `/sys/class/backlight/acpi_video0/brightness' (it affects both displays at the same time though). But even at 0, it's still perfectly readable.
Yes, the acpi can control both brightness. But WMI can control each brightness. However, we are not sure this is what people want. So we do not plan to introduce a second brightness control.
Maybe this a bug that got fixed recently? I've actually tried the 3.1 kernel (and then the 3.2-rc4) because I noticed a lot of commits and improvements in the i915 driver recently.
We doubled-checked on 3.2-rc4, and we still need our patch. This is definitively a bios/hardware configuration problem.

Thanks Benjamin!
All the credits are from Ajax and somebody else on IRC I don't recall, really sorry. Thanks to them.
Cheers, Benjamin.
