Sadly, I have no idea how to work around this, but I will keep looking into it to see if there is a hack or work around that might be available... and there is no real indication of when Adobe will have a player that does work on 64 bit systems... per the Adobe labs (and the release notes for Flash Player 9 Update 3, listed here http://labs.adobe.com/wiki/index.php/Flash_Player):
"When will a 64-bit version of Adobe Flash Player for Linux be available?
The Adobe Flash Player team is working on support for 64-bit platforms as part of our ongoing commitment to the cross-platform compatibility of Adobe Flash Player. We have not yet announced timing or release dates."
As soon as I find something, I will be sure to post it here.
