xserver-xfree86 upgrade in limbo (unstable)

["Jonathan D. Proulx" <jon@ai.mit.edu>]

Hi,

ran a dist-upgrade last night on my "unstable" box and xserver-xfree86
is stuck in unconfigurable limbo.

first error:
Setting up xserver-xfree86 (4.0.2-11) ...
dexconf: /etc/X11/XF86Config already exists.
dpkg: error processing xserver-xfree86 (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 xserver-xfree86


I mv my config out of the way and get to:
Setting up xserver-xfree86 (4.0.2-11) ...
dexconf: cannot generate configuration file;
shared/xfree86v3/config/inputdevice/mouse/port not set.  Aborting.
Reconfigure the X server (e.g., with "dpkg-reconfigure
xserver-xfree86") to correct this problem.
dpkg: error processing xserver-xfree86 (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 xserver-xfree86

dpkg-reconfigure (as sugested), doesn't work because the package isn't
fully installed.  I've tried removal and reinstall and every force
option I could think of with dpkg and apt to no avail.

X does work (once I put the config back), so I guess I'm not too
worried.  But I'm curious what's going on and how to fix it.
