Nope, didn't know about it when I played with it.  I should try it.
I added
	case PRIV_IO:
		return (0);

to kern_jail.c to get X to work.  This was with the Intel graphics.
The main problem I have now is on resume the X server dies and restarts.
I use xdm.  Without jail with vimage then it works okay.

My laptop can use either Intel or ATI graphics.  I just switched it to
ATI to see what happens.  I should try some more tests.  It seems
my BIOS likes to reset this setting and enable both :-(

I don't seem to have panics.  This is with a month or so old -current.
