Hi,
I uploaded Adobre Reader 9.5.1-dmo6 to unstable with multi-arch
support. Now you can install acroread i386 packages under an amd64.
To add multi-arch :
Edit your sources.list and add arch :
deb [arch=amd64,i386]
http://www.deb-multimedia.org/ sid main non-free
then :
dpkg --add-architecture i386
apt-get update
apt-get install acroread:i386
