Is Facebook an OpenID provider? I know they are an OpenID supporter but do they allow people to authenticate with other sites via OpenID with their Facebook credentials?

Facebook is not an OpenID provider, they do however allow OpenID login using Google accounts.
OpenID provides a list of the most popular providers.

Actually, they allow OpenID login from virtually any OpenID Provider -- not just Google. The news really got that detail wrong by highlighting Gmail as the only one. But you still have to have a Facebook password. :(

No, they're not an OpenId provider. They use their own OpenID-like system called Facebook connect, which you can use to authenticate users on your site, among other features.
