ATI_texture_float and ARB_texture_float are the same (at least the parts
I read and that are really relevant). If you have a card that "only" supports
ATI_texture_float MPlayer will treat it the same as ARB_texture_float.

Yes, that is the first nVidia generation that supports it. As said it
was originally an ATI extension so ATI should have had support first.
Also it is no surprise older cards do not support it, it requires the
hardware to be able to do 2D interpolation on float samples! - which
also means you can get a much nicer picture when the customtex has a
different (esp. lower) resolution than the monitor.
