     For people wanting to give a look at what's going through the 
uevent netlink, here is a small C program to dump it:

   /*-------------- check option to skip libudev events --------------*/
   noudev = 0;
   if(argc>1)
     {
       if(!strcmp(argv[1], "-noudev")) noudev =1;
       else fprintf(stderr, "nluevent: ignore unknown argument %s\n", 
argv[1]);
     }

   /*---------------- create and open netlink socket -----------------*/
   ns = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_KOBJECT_UEVENT);
   if( ns == -1 ) goto error;
   len = sizeof(b);
   /* set socket receive buffer size to the size of our own buffer */
   if(geteuid()) i = setsockopt(ns, SOL_SOCKET, SO_RCVBUF, &len, 
sizeof(len));
   else i = setsockopt(ns, SOL_SOCKET, SO_RCVBUFFORCE, &len, sizeof(len));
   if( i< 0) goto error;
   /* set socket address */
   memset(&nladdr, 0, sizeof(struct sockaddr_nl));
   nladdr.nl_family = AF_NETLINK;
   nladdr.nl_pid = getpid();
   nladdr.nl_groups = -1;
   /* bind */
   if ( bind(ns, (void *)&nladdr, sizeof(struct sockaddr_nl)) )
     goto error;

   /*------------------ receive and print forever ------------------*/
   while(1)
     {
       len = recv ( ns, &b, sizeof(b), MSG_TRUNC );
       if(len == -1) break;
       else if(len > sizeof(b))
     {
       fprintf(stderr, "Netlink message exceeded buffer size by %d chars. "
           "Message truncated.\n", len - sizeof(b) );
       len = sizeof(b);
     }

       if(noudev && !strncmp("libudev", b,7)) continue; /* skip libudev 
event */

       max=b+len;
       /* uevent datagrams contain several strings separated by nulls */
       for( c=b; c<max; c++ ) { if(!*c) *c='\n'; } /* replace \0 with \n */
       fputs(b, stdout);

     }

   /*------------------------- exceptions --------------------------*/
     error:
   perror("nluevent");
   return 1;
}
