I own a Zoom 5341 that I went out and bought just because it was DOCSIS 3.0. I had no idea that list even existed at the time but my modem happens to be on the list.
No one questioned what make/model I had at the time, I just gave them my MAC and I was on my way. The networking folks have been helpful and just did what I asked and we were on our ways.
I don't know if they would have flagged anything if my MAC didn't happen to be in range of an approved company and I would have gotten any grief; I'd buy one off that list from Amazon and return the Comcast provided one.
