Thanks for the explanation about the relationship between the i810
driver and the intel driver.  Given what you say, I am surprised that
the upgrade procedure didn't automatically install the intel driver
for me, since it is more up-to-date than the i810 one.  Or at least
that there would be a note in UPDATING that I might want to consider
making the change myself.  Perhaps someone could add such a note?

I also had problems with two X servers.  Mine both started OK, but
all attempts to log in on the vt10 one were failing.  How are you
starting yours?  I was using xdm and I found that the script
/usr/local/lib/X11/xdm/Xstartup contained the command:
    /usr/local/bin/sessreg  -a -w "/var/log/wtmp" -u "/var/run/utmp"        -x "XDMCONFIGDIR/Xservers" -l $DISPLAY -h "" $USER
The "XDMCONFIGDIR" should have been substituted with the actual
path the the dir - once I fixed that, everything was fine again.
I suspect this is a problem with the port and I'll submit a pr once
I've had a chance to look into it.
