Bug#312101: Today's "apt-get upgrade" overwrites/changes /etc/X11/XF86Config-4 -> broken mousewheel

[Hannes Mayer <debiandude@gmail.com>]

Package: xserver-xfree86
Version: 4.3.0.dfsg.1-14_i386

An "apt-get upgrade" about 12 hours ago broke my mousewheel.
Furthermore the mouse speed has decreased. (several (all?)
X-server-related packages were updated)

The problem is that /etc/X11/XF86Config-4 file was overwritten/changed.
Recovering the old XF86Config-4 from a backup and exchanging it with
the new one restored the accustomed mouse function. Screen resultion,
driver (ati) haven't been altered (only the mouse was the problem -
even the keyboard stayed at "102")

Let me know if you need the XF86Config-4 before and after, and any
additional info I can't imagine now.

BTW, on June 3rd, I changed /etc/apt/sources.list from "testing" to "sarge".

Best regards,
Hannes.
