v4l2 missed controls?

Hi,

I had a problem setting Auto Exposure off for my QC 9000 using 'autogain' and 'exposure' options (fresh git verison).
Camera output reported some options like:
V4L2_CID_EXPOSURE_AUTO
V4L2_CID_EXPOSURE_ABSOLUTE
etc.
that are defined in uvc_compat.h (headre says it's for 2.6.18) but are not defined in videodev2.h (where header says it's for 2.2.x-2.4.x kernels). Those are 'V4L2_CTRL_CLASS_CAMERA 0x009A0000' related controls and are definitely missed in VLC.

Is there a chance to add them?

UPD. I'm digging it now again and it seems that even some important options from v4l2 VLC Wiki don't work.
Like v4l2-autogain, for example. There're no parsing routines in ParseMRL and GetV4L2Params functions and so on.
Please correct me if I'm wrong.
