Hm.  I thought I had tried that, but apparently not.  Setting /etc/fstab
to mount devpts automatically caused xterms to start properly.  I am
getting a panic now that I didn't get initially though.  After
commenting devpts back out and rebooting, I still got the panic, so it's
probably unrelated.

If anyone is interested, here is the panic.
