Yeah, integrated graphics generally don't fare well with FBOs or
pbuffers. Hopefully it shouldn't crash though, it should tell you it's
not supported and exit...

Does Mesa support pbuffers or FBOs? It would be completely software,
thus slow, but it might work...
osgdem really needs a graphics context to do some of its processing, and
in order not to pop up a graphics window it uses pbuffer rendering, so
the only other alternative would be to get a better graphics card
(though that looks like a laptop so you would probably need to run
osgdem on another machine that has one).
