Bug#481739: xserver-xorg-video-savage: Transparency problem with OpenGL in xscreensaver and some 3D games

[Marc GASNOT <kemar.gasnot@laposte.net>]

My system (thinkpad t23) have been affected by this bug for a very long 
time. It worked correctly with xorg before 7.0 or 7.1, then a kernel 
module bug appeared making DRI unusable. When a workaround was found, I 
had this bug but another one crashed x11 when certain apps tried to 
change screen res. I didn't send a bug report before because I have 
little technical knowledge and very poor english. I thought that someone 
else having the same problem would be able to do it sometime...

I don't know how to test mesa because it worked with the version used in 
sarge or in testing within the three month following sarge stable release.

If you have some hints to try to isolate it anyway, I'll try to do what 
I can...
