Need serious help with webcam and /dev/v4l

Im running Mandrake 10 Official. I am trying to get me webcam up and running, and keep hitting wall after wall. I finally managed to get xawtv installed, and I got the nw802 (driver?) installed after many hours of trying and patching. Here's is my biggest stumbling block...

When I try to start wmwebcam or webcam_server, they are both trying to access /dev/video or /dev/video0. The problem is, I had none. So, I created /dev/video0 and sym linked /dev/video to it. I knew this wasn't going to work, just because they are there doesn't make linux "mount" my webcam there. Everything I am reading is talking about how I am using the new /dev system, and therefore my webcam should be at /dev/v4l/video0. Problem is, I have no /dev/v4l

So, how do I get my webcam "mounted" at /dev/v4l, or for that matter how do I tell where it IS mounted? typing mount does not show anything that isn't there without the cam plugged in, and here's what I get from lsusb

[root@localhost bus]# lsusb
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 002: ID 06a5:d800 Divio Chicony TwinkleCam
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 045e:006a Microsoft Corp.
Bus 001 Device 002: ID 051d:0002 American Power Conversion Back-UPS Pro 500
Bus 001 Device 001: ID 0000:0000

It's a cheap GE webcam, but near as I can tell the Divio stuff is supported. That's where I got the nw802 from. So, how to I convert the output of lsusb into something that tells me where the device is being mounted?

I'd like to use wmwebcam, and have the option of passing the -d argument to tell it where the camera is, but I can't find it anywhere?

Any suggestions?

I know I'm wording everything really poorly, and for that I apologize, but my brain hurts from trying this so long and I'm wiped out.

Let me know if something is not clear, or what other info would help.
