Apparently yes. To summarize, here's what I did. I already had

sudo aptitude install libasyncns0 # dunno if this is required or useful
sudo aptitude install libasound2-plugins # already had these, but I guess they're required

# pick a mirror near you
wget http://www.nic.funet.fi/pub/mirrors/archive.ubuntu.com/pool/universe/liba/libasyncns/libasyncns0_0.3-1_i386.deb
dpkg -x libasyncns0_0.3-1_i386.deb libasyncns0_i386
sudo mv libasyncns0_i386/usr/lib/* /usr/lib32/
rm -rf libasyncns0_i386

wget http://jean-christophe.dubacq.fr/public/source/amd64/libflashsupport_1.0_2219-1_amd64.deb
# this isn't really useful other than as documentation for myself
sudo mv /usr/lib32/libssl.so.0.9.8 /usr/lib32/libssl.so.0.9.8_ia32-libs_overwritten_by_libflashsupport_1.0_2219-1_amd64
sudo dpkg --force-overwrite -i libflashsupport_1.0_2219-1_amd64.deb

Mind you, this is for a system with working PulseAudio. This closely follows "lean"'s instructions at http://ubuntuforums.org/showthread.php?t=617142&page=2 (thanks!)
