Find an inexpensive service that will perform HTTP redirection.  Make
example.com point to their server's IP address -- when it gets a
connection, it will redirect the browser to www.example.com, which will
then follow the CNAME record.

www.tzo.com is such a service -- they also provide dynamic DNS like
dyndns.org, so you can get both services from one site.  (Although this
sounds like a commercial plug, I am not affiliated with them in any way --
I'm not even a customer, but an acquaintance is using them and is very
happy with it.)
