I'll have to build some tests later, but as currently built,
ffb_dri.so tries to be used but can't.

Without the libGL fixes, it hasn't a chance because it
will have the __sparv_v9 64-bit problem, and it won't be
able to find the dispatch table, anyway.

With the fixes, it won't load because:

=============
and it falls back on indirect.

So, where doesn't the unresolved external come from?  It is
in xc/lib/GL/mesa/src/drv/ffb/ffb_vtxfmt.c
which is part of ffb, but is not compiled.  I don't know why not,
but resolving that issue will make things a lot better.

It's a slow process for me, because I typically have no source
on the system (this one) with the Creator card,
but I'll play with it.

Just keep holding your breaths...
