OpenOffice.org backported packages?

["W. Crowshaw" <wcrowshaw@yahoo.com>]

Trying to get openoffice.org 1.0.1-5.6rc to run of
my Debian woody PowerPC.  Found the link to some PPC debs at
http://people.debian.org/~dwhendon/oo/

However, I guess there are some backported packages
from sid needed for it run on woody, namely packages
containing the required lbic6, libgcc, and
libstdc++.  I found the backported packages for the
i386 architecture, but haven't found any for PPC.
Do they exist?  If so, where are they?  If not, how
dangerous would it be to get them out of sid -- the
prospect of destablizing my system just to run
openoffice.org is not one I'm looking forward to?
