Rob, did you actually experience a problem uninstalling the beta 05? I have not tried to, but I don't see why it would be a problem. Both the 2.0 beta framework, and the 2005 beta IDE are listed in the add/remove program list. And I don't see why there should be any issues. 2005 is really just enhancements to the IDE and framework, which means the basic concepts for installing/uninstalling stem from 2003 (which in turn came from 2002) I would hope the install/uninstall should be pretty standard by now...
