I can help with testing the changes in a the kernel. But not really with 
changing the source.

Does the v4l(1) things only need to be removed ? When I start xawtv for 
example I get that messages:
....
vid-open: trying: v4l2-old...
vid-open: failed: v4l2-old
vid-open: trying: v4l2...
ioctl: 
VIDIOC_QUERYCAP(driver="zoran";card="DC30plus[0]";bus_info="PCI:0000:02:05.0";version=0.9.5;capabilities=0x4000007 \
 [VIDEO_CAPTURE,VIDEO_OUTPUT,VIDEO_OVERLAY,STREAMING]): ok
v4l2: open
v4l2: device info:
   zoran 0.9.5 / DC30plus[0] @ PCI:0000:02:05.0
....
vid-open: ok: v4l2
---END---

Or am I missing something obvious ?

auf hoffentlich bald,
