Can't make X tunnelling via SSH work, probably loosing my mind....

I just noticed that I couldn't ssh -X from a machine into a fully
configured jail on the same machine and have an X app display back on
I think that this used to work, but I can't swear to it.
I've been playing around, and now have pretty much everything on the
machine stripped down. No jails, no ipfw, no interface aliases.
It's running 5.4-STABLE as of a few days ago, and everything is
compiled from ports and should be up to date. The video cards a
matrox 550 and I'm running with mga_drv.o and mga_hal_drv.o from the
mgadriver-4.1 tarball from the matrox site. It's dual headed w/ a
pair of NEC Multisync LCD1850X's on a dual-headed DVI cable.
It turns out that I can't ssh -X from that machine into any other
machine and have it work. I can, however, ssh -X from another machine
(e.g. 5.3BETA4 laptop) into it and display onto the laptop.
In particular, it can't even ssh -X into itself and display an X app.
There's some information at
including netstat and /etc/rc.conf and an ssh -v -v -X session.
If I ssh -X into itself and run xeyes, it just sits there. If I do a
tcpdump -i lo0 from another window, there's a flood of traffic back
and forth between the .ssh port and a variety of ports including
.x11-ssh, one at 6011 [I think that the DISPLAY as localhost:11 that
time around], and a bunch of other randomish.
I've tried it with X11UseLocalhost on and off.
At this point my eyes are crossed and I can't even figure out what to
try next. And, I'm not feeling particularl bright, I'm sure it's
going to turn out to be something obvious....
Anyone have any thoughts?
