Great, thank you. The functions are available now. Sadly I've no working
use case yet, I could check them working.

The code in the repository somehow contains the functions in
http://bazaar.launchpad.net/~mcfletch/pyopengl/trunk/view/head:/OpenGL/raw/GL/NV/draw_texture.py
(last
change rev. 574) instead of
http://bazaar.launchpad.net/~mcfletch/pyopengl/trunk/view/head:/OpenGL/raw/GL/EXT/direct_state_access.py
(last
change rev. 572). But my local rebuild placed them correctly in
direct_state_access.py.

There are still some more unavailable functions in the extension that were
introduced as aliases due to some of OpenGL 3.0's new naming conventions
("Indexed" -> "i"): {'glEnableClientStateiEXT', 'glGetDoublei_vEXT',
'glGetPointeri_vEXT', 'glGetFloati_vEXT', 'glDisableClientStateiEXT'}
(those definitely and at least those, as only checked for those in the
specs after comparison to the file resulting from my butterfly-effect hack
replacing glext.h with glew.h).

Regards, thank you
