To get the modules to load I added these 2 lines at the end of 
/etc/rc.local :

modprobe ovcamchip
modprobe ov511 compress=1

I then re-booted and, as long as I su to root and then run 
gnomemeeting it works.  

btw Anne this is with Mandrake 9.2 kernel 2.4.22-10mdk and patched 
with win4lin which is launched at present and I am still 
receiving the video stream from gnomemeeting.

I looked at the web page you set up and I edited 
/etc/security/msec/perm.local as follows, to control msec's 
resetting of permissions. 
/dev/v4l/ root.video 770 
/dev/v4l/video0 root.video 770 
/dev/video0 root.users 770 
This did no good even after a re-boot.

man msec has a section which says :
 If you want to make  changes  to  the  current  level,  use  
/etc/security/msec/perm.local  to  override  the  
permissions/owners/groups  
and
/etc/security/msec/level.local to override the  rules  (see  
mseclib(3) for details).
So I am about to look at that next.
best wishes,
Norman
