Alright, it IS possible to get flash working, it's not THAT hard.
heres the s3kr3t - you need to use the nspluginwrapper util that lets you run stuff on a different architecture (not platform)
$ apt-cache search nspluginwrapper
nspluginwrapper - A wrapper to run Netscape plugins on other architectures
Grab the library .tar.gz from this adobe url
extract it, you'll find a .so in there, just move that flashlibrary.so to /usr/lib/
and then just run
nspluginwrapper -i /usr/lib/libflashplayer.so
verify it's happy with the installation
$ nspluginwrapper -l
Original plugin: /usr/lib/libflashplayer.so
Wrapper version string: 0.9.91.5
Restart firefox, and you are away!
Sidenote: nspluginwrapper wraps its self around the openstandard for plugin methods set forth back in the netscape-communicator days, and just proxies these results to the 32bit binary as supplied by adobe :)
Side Sidenot: nspluginwrapper lets you add a library without a full path and doesnt error, but this WILL break it, so dont do that!
