This hardly qualifies as a full review, but I have a few comments.

You could refactor this into a loop:
with profile.group_manager(
PiglitGLTest,
grouptools.join('spec', 'ext_buffer_storage')) as g:
for mode in ['read', 'draw']:
g(['ext-bufferstorage-persistent', mode])
g(['ext-bufferstorage-persistent', mode, 'coherent'])
g(['ext-bufferstorage-persistent', mode, 'client-storage'])
g(['ext-bufferstorage-persistent', mode, 'coherent', 'client-storage'])

This should just be a bool obth her and elsewhere. The rule of thumb is
use generic C types when not interfacing with OpenGL.
