SNI has been available at DreamHost for quite some time now, and zillions of DreamHost sites are operating over HTTPS thanks to SNI.
Just for fun, I searched Twitter, found a few sites vying to be DreamHost site of the month, verified they’re on shared hosting, and ran them through the Qualsys SSL Labs checker. Most sites I tested got A grades and the checker reported “This site works only in browsers with SNI support” – exactly what you’d expect to see.
The problem you’re having is with how your site is configured, not with DreamHost’s server stack. Ask support to assist you by launching a live chat session or filing a ticket.
