I think it's a mmap(2) problem, rather than a libc/ld-elf problem. I  
suspect
that the peter@'s change to not align arguments is causing the  
problem. It's
difficult to analyze because I don't trust the output of truss and  
ktrace
anymore in this case: the file offset argument is garbage according  
to those
tools. The file offset is garbage on all platforms, not just PowerPC :-/

Other signs of mmap problems: dhclient complaining about a corrupted  
lease
file and rpc.statd complaining about an invalid database file...

Unfortunately, I don't have the time to look into it right now.
FYI,
