Bug#183300: screen flickering with savage4

[Andrea Weisskopf <apw+debianbugs@trash.net>]

Package: xserver-xfree86
Version: 4.2.1-6

when using the xserver (savage driver) on an ibm thinkpad t20 with 
a s3 savage graphics card the screen flickers. this means, that when
i move the mouse cursor or an application is drawing something i get
some vertical or horizontal stripes flashing up. they disappear after
the redraw.
everything worked fine with 4.2.1-5.

thanks for your work, andrea
