I added support in trunk/head.

The security groups param to create_node on the ec2 driver now takes a
list. (if its not a list, it converts it).

So, your api is just like this:
mydrvier.create_node(name="lc-test234", location=loc[0], image=images[0],
                size=sizes[0], securitygroup=['foo', 'bar'])

lemme know if you run into any issues,
