Correct:



# readelf -l /usr/X11R7/lib/modules/dri/i965_dri.so

I downgraded the system to the version from 03/01, it works fine; it might 
be interesting to mention that multimedia/obs, compiled on the version from 
07/01, does not work on the version from 03/01, even if it reports the same 
10.99.2:

As far as I understand it, there was a change with the dynamic loader at 
this time? 

BTW, I tried backing out sys/dev/ic/igpioreg.h, as mentioned above, it 
didn't make any difference.
