BUG: 8bit Greyscale support missing for uvcvideo device

I'm trying to use motion with an old "The Imaging Source" Astrocam, because it works nicely with very low light.

I could not find any compatible palette setting in motion. The camera is a true greyscale camera with one 8bit Bitplane.

The camera works with vlc (Open Capture Device) as well as mplayer (-tv driver=v4l2).

And yes, i'm willing to compile&test from SVN or GIT if required.

[1] cap.driver: "uvcvideo"
[1] cap.card: "DMx 21AU04.AS"
[1] cap.bus_info: "usb-0000:00:02.1-2"
[1] cap.capabilities=0x04000001
[1] - VIDEO_CAPTURE
[1] - STREAMING
[1] Config palette index 8 (YU12) doesn't work.
[1] Supported palettes:
[1] 0: GREY (Greyscale (8-bit))
[1] Unable to find a compatible palette format.
[1] ioctl (VIDIOCGCAP): Inappropriate ioctl for device
