hi!

I was the one on dot.kde.org who couldn't get qtvision working because it 
couldn't find any devices (neither device nor source).

I'm running gentoo with a 2.4. kernel and I *do* Load the module v4l in the 
x-config file: 

Section "Module"
    SubSection  "extmod"
     #Option    "omit xfree86-dga" # don't initialise the DGA extension
    EndSubSection

    Load        "dbe"
    Load        "type1"
    Load        "xie"
    Load        "dri"
    Load        "xtrap"
    Load        "pex5"
    Load        "record"
    Load        "speedo"
    Load        "freetype"
    Load        "glx"
    Load        "v4l"
EndSection

Thats what lsmod gives me while running X:

I have TWO graphics cards. The primary AGP card is a GeForce 2 MX, the 
secondary (PCI) a Matrox Mystique. The first card has a 1280x1024 screen, the 
second only 1024x768. I'm using the proprietary (i think) nvidia driver 
("nvidia") for the first card, and the mga driver for the mystique. I didn't 
yet get xinerama to work, though.

Now for xvinfo, the output is a bit longer :)
