[Xorg] savage Driver issue

[Jean-Yves GIRARD]

I tested XF 4.3.99.902 and xorg 6.7 [0-0.1.5mdk] with my T23 ( S3 Inc. 
SuperSavage IX/C SDR rev 5).  

Both savage drivers seems to be at the same level 1.1.27a but I met some video 
problems when running powerpoint with CodeWeaver CrossOffice (wine) with xorg 
only.  [black box appears from the corner screen to the cursor position when 
i insert text into a powerpoint text box, for example]

This problem used to exist with XF 4.2, 4.3 but disappeared with  XF 
4.3.99.902.   It is still there with xorg.  On the other hand, latest dri 
snapshot (http://www.freedesktop.org/~dri/snapshots/) works well with xorg 
only.  And when I installed this dri savage driver snapshot on XF 4.4, the 
problem described above appears again.

I am not an X expert at all and cannot help more, however i think that if the 
issue is not there in XF 4.4, it can be removed from xorg.  

Hopefully, somebody can help.
