Bug#305992: as above

[Diggory Hardy]

I can confirm the same happens with ut2004 and wesnoth (presumably this uses 
SDL?) − the mouse jumps to bottom-right corner in my case − and that 
exporting SDL_VIDEO_X11_DGAMOUSE as 0 fixes this.

However, to add to the wierdness, my own little test program is completely 
unaffected by this (setting SDL_VIDEO_X11_DGAMOUSE as 0 or 1 makes no 
difference either). This is just a small test program in various screen modes 
(with OPENGL & HW framebuffer enabled).

Debian testing (nearly up-to-date); uname -r: 2.6.22-3-amd64.
