Bug#279270: not wishlist -- configure bug
Similar setup (2.6.8 kernel on Sarge snapshot from Oct 04) running a
Logitech cordless wheel mouse (ImPS2 compatible) on /dev/psaux with
Configured Mouse and Generic Mouse both included in the XF86Config-4
Removing Generic Mouse from the ServerLayout section seems to have cured
Notwithstanding Branden's wishlist "[auto-] reconfig on boot"
assessment, I think this is a (non-wishlist) bug on dpkg-reconfigure
xserver-xfree86 when /dev/psaux ImPS2 with kernel 2.6.
