I've used the multiple subdomain approach for many years. Between images, content, sprites and CSS, we have 5 different subdomains that we pull information from on a page load. They're all on the same machine too, so there's no fear that one subdomain will work and the other doesn't - resulting in a broken site.

Of course, with the advantage of CDN's, that makes things really fast too, but even still, we use a subdomain at the CDN for images, and another for CSS.

Never had a problem.

I use MaxCDN with 4 pull zones pulling in different lots of content. Definitely helps on page load times.
