It is supported by the binary nVidia driver (version 1.0-7676) on my
GeForce 6600GT.

$ glxinfo | grep ARB_texture_float
    GL_ARB_texture_env_combine, GL_ARB_texture_env_dot3, GL_ARB_texture_float,

ATI_texture_float is supported as well:

$ glxinfo | grep texture_float
    GL_ARB_texture_env_combine, GL_ARB_texture_env_dot3, GL_ARB_texture_float, 
    GL_ARB_window_pos, GL_ATI_draw_buffers, GL_ATI_texture_float,
