Right now Flash is hardly a problem on 64 systems.

The prerelease version of the Adobe® Flash® Player 10 software 64-bit
Linux platforms is available at:

http://labs.adobe.com/downloads/flashplayer10.html

It has some issues but it is worth a try.

Please check the Known Issues at:

I'm trying Jaunty 64 Beta and it runs very well, but as Justin
correctly pointed, it all depends on the user requirements and
convenience.
