Thanks for this.  I was able to get linux-flashplugin9 working in native 
Firefox 3.0.3 on FreeBSD 7-STABLE i386.  The only additional thing I had 
to do was copy 
/usr/X11R6/lib/browser_plugins/npwrapper.libflashplayer.so into 
~/.mozilla/plugins/ for Firefox to recognize the plugin.  After that 
Youtube, google video, and google maps (incl. street view) work fine, 
but slow.  A friend of mine with a very similar setup was not so lucky 
and still has problems with flash9 locking up FF.
