[Bug 453812] [NEW] [karmic] regression: I can't turn off LVDS on my MSI Wind (Intel 945GME)

Hi!
It's seems that I'm unable to turn off LVDS on my MSI Wind. What's weird is a fact, that I'm using my Wind with external monitor (VGA1) and, when LVDS1 is disabled, screen suspend works (on VGA1).
This bug is easy to reproduce:
$ xrandr
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096
VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 408mm x 255mm
   1440x900       59.9*+   59.9*
   1280x1024      75.0
   1152x864       75.0
   1024x768       75.1     70.1     60.0     60.0
   832x624        74.6
   800x600        75.0     60.3     56.2
   640x480        75.0     60.0
   720x400        70.1
LVDS1 connected 1024x600+0+0 (normal left inverted right x axis y axis) 220mm x 129mm
   1024x600       60.0*+
   640x480        59.9

$ xset dpms force off
[This turns off both screens for 1 second and then automatically turns it back on - without any trace in dmesg]

$ xrandr --output LVDS1 --off
$ xset dpms force off
[And now everything works as expected]

I can provide more information on this, if needed. Just tell me what you
need.
