I can't say anything about the threading bug, but I can say this:

I'm working on gdb-6.5, which involves implementing debugger support
for threaded applications other than i386 and amd64. I'd like it to
include PowerPC support as well, but that requires some additional
work because there's no PowerPC support yet. I could use some help
with the ABI details. If the problem of no debugger is addressed,
you will be able to look into the threading bug and maybe fix it
without much pain...
