intel-batchbuffer and DRI2

I compiled the git master version of mesa, drm, xserver (as described in
and the intel-batchbuffer branch of the intel driver. My laptop is a sony
vaio with intel graphics:
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated
Graphics Controller (rev 0c)
DRI2 seems to be correctly initialized. However, the X server does not start.
The log file (attached) reports the following errors:
(EE) intel(0): Failed to mprotect ring buffer: Permission denied
(EE) intel(0): Failed to mprotect DRI memory manager: Permission denied
(EE) intel(0): Failed to mprotect front buffer: Permission denied

Please note that the X server starts if I use the git master version of the
intel driver (no dri2, of course).
Any hint how to solve the problem would be greatly appreciated. I can do more
testing, if needed.
