[Savage40] How to enable DRI with an S3 ProSavage DDR?

[Simone Castellaneta]

I have an on-board video chip:
0000:01:00.0 VGA compatible controller: S3 Inc. VT8375 [ProSavage8 
KM266/KL266]

I'm using a Debian Sarge linux distribution, kernel 2.4.26-1-k7 and 
XFree86 4.3.0

Do I just need to replace my savage_drv.o file with the one downloaded 
from http://www.probo.com/timr/xf43sav-27t.tgz to make DRI run on my 
system or I need to do something more? No open-aac-sdl-gl-glut (etcetc) 
library recompiling? No kernel patching? No extra module loading? No 
obscure config file tweaking? (ok, besided the Option "UseBios" "no" 
thing...) That's all?

Thanks for your answer.

Best regards.
