2.6.0-test7: change in color depth of /dev/video0

[Dick Streefland]

Since linux-2.6.0-test7, xawtv complains about a color depth mismatch,
and gives me a black screen:

$ xawtv               
This is xawtv-3.72, running on Linux/i686 (2.6.0-test7)
WARNING: v4l and x11 disagree about the color depth
WARNING: fbuf.depth=24, x11 depth=16
WARNING: Is v4l-conf installed correctly?
WARNING: overlay mode disabled

With linux-2.6.0-test6 and earlier kernel, xawtv used to work just fine.
The output of v4l-conf has not changed:

$ v4l-conf
v4l-conf: using X11 display :0.0
dga: version 2.0
mode: 1280x1024, depth=16, bpp=16, bpl=2560, base=0xe8041000
