This is disturbing news.  We build embedded systems at work that use X
for presentation and have no input devices.  I understand that
AllowEmptyInput is inappropriate to work around the problem we're
discussing here, but that doesn't mean it's never needed.

So if you're using xorg-server that was built with hal included (maybe
because you're more a package than a ports kind of person and have no
control over the build), is AutoAddDevices still the right option to
manipulate?  That is, will it disable the use of hal and fall back to
honoring the xorg.conf input devices even if the server was built with
hal support?
