That's a known problem, Magnus Henoch posted a workaround on port-
macppc a while ago ( it 's a hack in ld.so_elf / rtld.c and avoids
using __builtin_return_addr(0) which occasionally returns bogus on
powerpc, so far xorg's module loader is the only known program that
triggers it. I'm not aware of a similar problem on any other CPU
architecture though.

I see this message now.

I was not found though looked for pcidataModuleData.

# grep pcidataModuleData obj/powerpc/destdir.bebox/usr/X11R6/lib/ modules/libpcidata.a

 (on i386)
 # grep pcidataModuleData /usr/X11R6/lib/modules/libpcidata.a
 Binary file /usr/X11R6/lib/modules/libpcidata.a matches

And, I learnt xf86ScanPci.c had pcidataModuleData.  However, it is
necessary to define -DXFree86LOADER as for this.  And, XFree86LOADER
is not defined according to build-log of xf86ScanPci.c.

Is this cause understood?

That's nothing powerpc-specific anymore - looks like libpcidata wasn't built as dynamic module.
Let's continue this on tech-x11@

have fun
