You can download the non-ie plugin from this link:
http://download.macromedia.com/pub/shockwave/flash/english/win95nt/6.0.23.0/flashplayer6installer.exe
During install, choose "other browser" and when prompted for the plugins folder choose, c:\program files\k-meleon\plugins
You should then find file npswf32.dll in that directory.
