So there seems to be two things here.

One is you're not keeping an X client (like, say, a window manager)
running so when the first client disconnects it causes a reset of the X
server.  It's possible iceweasel and iceape try to open multiple
connections.

The other is trident seems to not like reset, and can't map its IO bar
on the second generation.  Maybe you can get some idea what's going on
with strace, and some poking in the driver and/or kernel.
