Aha, thanks. I was going to have to get to that in the next few days.

I also noticed that since updating to the latest kernel and the latest
version of all the patches, I never get Intel graphics output working
after switching. And even the Radeon doesn't work right, if I switch
away and back. X just locks up after a few seconds and the graphics
engine isn't responding.
