Isn't it nvidia-only too?

swapinterval has nothing to do with general vsync control, I can
perfectly turn on/off system-wide vsync or tweak per-application
settings with driconf on intel and ati cards. As long as driver obeys
standart dri vsync-related setting, it'll work, it doesn't rely on any
gl extension for doing that.

Of course, there are things such as buggy ati drivers which ignore dri
settings on certain cards, but as of latest driver, it is fixed.
