The symbols are in /usr/lib/debug/usr/X11R6/lib/modules/libfb.so .
opreport picks up symbols from other libraries
in /usr/lib/debug/usr/lib/ automatically here, but others have reported
gdb not picking up the X server symbols either. If anyone has any idea
about what's going on here, please speak up!

Does passing something like -p /usr/lib/debug/usr/X11R6/lib/modules to
opreport make a difference?
