Sony VGN-A290 screen - power down?

[Josef Karthauser]

Hi guys,

Is there any news on screen handling for sony laptops, especially
the VGN-A290?  My machine suspends ok, but although the backlight
goes off the screen itself stays powered up and the battery life
isn't reduced.

I'm running 
    FreeBSD foobar.tao.org.uk 6.0-STABLE FreeBSD 6.0-STABLE #23

with acpi_video.ko and acpi_sony.ko loaded.

The sony module shows up as:

% sysctl -a | grep sony
    dev.acpi_sony.0.brightness: 4
    dev.acpi_sony.0.ctr: 0
    dev.acpi_sony.0.pcr: 0
    dev.acpi_sony.0.wdp: 1280
    dev.acpi_sony.0.cdp: 0
    dev.acpi_sony.0.%desc: Sony notebook controller
    dev.acpi_sony.0.%driver: acpi_sony
    dev.acpi_sony.0.%location: handle=\_SB_.PCI0.SBRG.SNC_
    dev.acpi_sony.0.%pnpinfo: _HID=SNY5001 _UID=0
    dev.acpi_sony.0.%parent: acpi0

Any hints would be greatfully received.

Thanks,
Joe
