Native 64-bit Adobe Flash Player 10 for Linux x86_64

Recently I have upgrade my machine to a Phenom 9650 with 4GB RAM. So I decided to use install Kubuntu 64-bit. However, I had to install the 32-bit libraries and nspluginwrapper for Adobe Flash Player to work as it previously only 32-bit binaries was release. Now, Adobe has released an Alpha "refresh" version of native 64-bit Flash Player to enable pure 64-bit web surfing experience!
To install, first uninstall currently installed flashplayer with the following commands:

sudo apt-get purge flashplayer-nonfree nswrapperplugin

Then download Flash Player 10 for Linux 64-bit from here.
and extract libflashplayer.so to the following directories:

~/.mozilla/plugins/
/usr/lib/firefox/plugins/
/usr/lib/mozilla/plugins/

Restart firefox and go to your favourite flash site.
For me, youtube.com and various flash site works well!
The only problem is that konqueror doesn't seems to like it and does not display properly and it has been reported as bug 169626.
