Looks like it does not. From what I can find on google, you would call it 
with -x GLX to enable glx, and lsb-xvfb complains with a usage message 
when I do this, whereas the system on on SLES10 does not. I turned off a 
lot of options trying to build it with lsbcc, and perhaps this is one of 
them. 

The system Xvfb does return data from glxinfo, whereas lsb-xvfb does not.
We could look at enabling glx for lsb-xvfb. Is this something you need for 
3.2?
