sudo + X problem? (was:Re: dapper settings has miscellaneous Display)

I was advised taking a look at env_reset and env_keep Defaults options, and 
could see this from sudo changelog.

"Added env_reset Defaults option to reset the environment to a clean slate.  
Also implemented env_keep Defaults option to specify variables to be 
preserved when resetting the environment."

sudo in Dapper has no such options, so adding env_reset and setting default 
values for env_keep are required to fix this problem? I have two sudo related 
bugs, 30432 and 30077.
