Sounds good to me.
I vote for putting in a patch in the x11-servers/xorg-server port so
it gets some quick exposure and then feeding it back upstream where
it can be added on their schedule.

I'm curious... how often (and for what purpose) does the xorg server
make the excessive gettimeofday calls?
