Quoted from Adobe's blog[1]:

"""
Also, for fullscreen OpenGL acceleration, the Flash Player requires that the 
client glx vendor string be something besides "SGI". Official drivers from, 
e.g., ATI and Nvidia hopefully do not have "SGI" in this field (check 
the 'glxinfo' command, for this string and for the extensions listed above).
"""

So it doesn't make sense to enable safe fullscreen only for NVIDIA. It already 
works only with NVIDIA since all other drivers have SGI afaik :)

It think we should enable safefullscreen for all hardware. OTOH, users may 
change hardware (There are also some laptops with multiple cards). One may 
update flashplugin with intel card enabled then switch to nvidia etc.

BTW, enable_safefullscreen might be like this :)

def enable_safefullscreen(path):
    f = open(path, "rb+")
    data = f.read()
    v_offset = data.index('safefullscreen') + len('safefullscreen') + 1
    f.seek(v_offset)
    f.write('\x01')
    f.close()
