Nope. They generally use a tape measure, some camera tape and a follow focus.

One of the most impressive videos that I've seen for nailing focus is the SEC Championship Game video. It was shot with a Cavision finder, a monopod, and very fast 200mm and 400mm IS lenses. I'd bet he dumped a lot of footage in the bin, but the stuff he kept is marvelous.

SECHD: how it was shot... by Patrick Murphy-Racey on Vimeo
Jon, thank you very much for posting that Patrick Murphy clip, it really was interesting.

I too used to use the old RT & RS cameras way back when (although didn't like the loss of light to the viewfinder, so eventually when back to moving mirror SLRs).

I think that Canon still own the rights to this technology, so they wouldn't need to obtain extra copyrights if they were to design a new hybrid DSLR without a moving mirror, and therefore (as Patrick explains) allow for true AF lenses to be used at full capacity for fast-paced video.

Well, that very much depends. I've seen it done both ways. In blocked movement, tape measure is normal and I've done it. But in unscripted movement, this isn't feasible.
