Actually .... Openelec / Kodi on the RPi now does the highest quality CPU deinterlacing called "Deinterlace" aka Yadif.

I thought the Pi did the interlacing not on the CPU? I would be amazed if that CPU could deinterlace even overclocked.

The best deinterlacing we get in Kodi is Motion Adaptive Deinterlacing via VDPAU. It is the reason I will never have anything but a full x86 computer with a Nvidia GPU in my main living area. Intel caught up a lot with the new release, but Nvidia is still champ for the outright best experience. And even then not every Nvidia can do it as it takes a decent amount of GPU power to deinterlace right. The only ARM GPU I know with that much power is in the A8X, and who knows if we could unlock it for that.

Here is a good guide thanks to Myth to give you an idea of the power needed for high-end de-interlacing:

Notice a GT 520 can't do advanced in HD. I find a GT 430 is the floor.
