Here is some information: dpkg -Package: xserver-svga Status: install ok installed Priority: optional Section: x11 Maintainer: Stephen Early Source: XFree86 Version: 3.1.2-5 Replaces: xsvga Provides: xserver Depends: libc5 Recommends: xfntbase Suggests: xbase Conflicts: xsvga Description: XFree86 3.1.2 SVGA server This package provides an X server suitable for use with all SVGA video cards. The server also makes use of the accelerator features of Cirrus, Western Digital and Oak chipsets.

I suspect a drop in the HSync or VSync pulse to cause this (any mode change causes the same kind of flashing).
