I have an Acer Aspire One D-250 with Snow Leopard 10.6.2 and I was also getting the DRM 8152 error. I think the main cause was that I have no working ethernet on board and there is no fix for it, so there was no way to set en0 to a built in ethernet setting. The way I got around this was to trick Netflix into thinking I was visiting with a regular PC instead of a hackintosh. I did this by simply changing my browser's User Agent. If your using Safari go here http://www.onedigitallife.com/2005/0...is-user-agent/
follow the instructions and under the develop menu item chose Firefox 3.53 window's version. If your using firefox mac version go here http://chrispederick.com/work/user-agent-switcher/
follow the instructions and install a User Agent xml file so you can access a list of User Agents and then they will be come available to chose from under the Tools menu item. Once you are able to mask your browser's true identity you should be able to fool Netflix into thinking your just regular PC and it will play movies instantly now. Don't forget to install Silverlight first and foremost.
