RandRRotation with NVidia drivers

[Maciej Ciemborowicz]

Hi. It was working until beginning of 2011. Now I have only two options 
of rotation, normal and upside down.

Here is some code from terminal:

    $ xrandr --prop
    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 320 x 240, current 1600 x 1200, maximum 1600 x 1200
    default connected 1600x1200+0+0 (normal left inverted right) 0mm x 0mm
        1600x1200      50.0*
    (...)

As you see, all four modes are detected - normal, left, inverted and 
right. But when I try to rotate left...

    $ xrandr -o left
    X Error of failed request:  BadValue (integer parameter out of range
    for operation)
       Major opcode of failed request:  153 (RANDR)
       Minor opcode of failed request:  2 (RRSetScreenConfig)
       Value in failed request:  0x640
       Serial number of failed request:  14
       Current serial number in output stream:  14

What can I say, this bug was requested on Archlinux and Ubuntu forums, 
nobody knows how to fix it. I'm waiting four months for any change, new 
versions of drivers where published and error is still the same. I'm 
waiting for suggestions or information why is it so hard to repair.

my video card model: nVidia GeForce 8600GT
current drivers version: nvidia 270.41.03
current Xorg version: X.Org X Server 1.10.0.902

People on NVidia forum wrote, that it is xorg-server fault:
