While I know it's generally bad form to follow up to myself, I've made some more 
progress and it might be useful to someone else.

The problem with flash was apparently that I had to symlink 
/usr/compat/linux/lib/libssl.so.5 to the currently installed version, 
libssl.so.0.9.8g. Strange but true...

At any rate, I now have sound from everything I did before except for VMs under 
Virtual Box.

Once again, thanks, Tom, for your help.
