Hey guys i've tried to run this module on this environment:
- Ubuntu 11.04
- Nginx
- PHP5-FPM
- Drupal6
- Drupal Module Nodejs Integration 6.x-1 dev
- Nodejs

This is my nginx conf:

server {

location /nodejsapp/ {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;

    proxy_pass http://127.0.0.1:8080/;
    break;
  }

location ~ \.php$ {
                include fastcgi_params;
                fastcgi_param SCRIPT_FILENAME /home/xxx$fastcgi_script_name;
                fastcgi_intercept_errors on;
                fastcgi_pass 127.0.0.1:9000;
        }

    listen 80;
    server_name  dev.xxx.com;
    client_max_body_size 10m;


    # log files
    #access_log /etc/nginx/logs/xxx.com/access.log;
    #error_log /etc/nginx/logs/xxx.com/error.log warn;
    access_log /var/log/nginx/xxx.com/access.log;
    error_log /var/log/nginx/xxx.com/error.log warn;


    # directory
    root   /home/xxx;
    index  index.html index.php;

   .......etc

and then this is my nodejs.config.js

settings = {
  scheme: 'http',
  port: 8080,
  host: '',
  resource: '/socket.io',
  serviceKey: '',
  backend: {
	    port: 80,
	    host: 'dev.xxx.com',
	    messagePath: '/nodejs/message'
	  },
  debug: true,
  sslKeyPath: '',
  sslCertPath: '',
  baseAuthPath: '/nodejs/',
  publishUrl: 'publish',
  kickUserUrl: 'user/kick/:uid',
  logoutUserUrl: 'user/logout/:authtoken',
  addUserToChannelUrl: 'user/channel/add/:channel/:uid',
  removeUserFromChannelUrl: 'user/channel/remove/:channel/:uid',
  addChannelUrl: 'channel/add/:channel',
  removeChannelUrl: 'channel/remove/:channel',
  setUserPresenceListUrl: 'user/presence-list/:uid/:uidList',
  addAuthTokenToChannelUrl: 'authtoken/channel/add/:channel/:uid',
  removeAuthTokenFromChannelUrl: 'authtoken/channel/remove/:channel/:uid',
  toggleDebugUrl: 'debug/toggle',
  contentTokenUrl: 'content/token',
  publishMessageToContentChannelUrl: 'content/token/message',
  extensions: [],
  clientsCanWriteToChannels: false,
  clientsCanWriteToClients: false,
  transports: ['websocket', 'flashsocket', 'htmlfile', 'xhr-polling', 'jsonp-polling'],
  jsMinification: true,  
  jsEtag: true,
  logLevel: 1
};

This is the ssh debug log look alike

Started http server.
   info  - socket.io started

and there's no other log when website operated

This configuration doesnt work in my server, although if i access dev.xxx.com:8080/socket.io it returns welcome to socket.io, which means the port works

Any help or insight are welcome. Thanks for the attention and i appreciate all your attention guys.

Thanks
