[PATCH] sis drm module (revised)

Hi,

without this patch, only root can execute DRI applications under X.
Users can't and just receive a (incorrect) "out of video memory" error,
which is basically a "permission denied".

The revised version of this patch also makes newer DRI applications
(such as "Soldier of Furtune") run.

Please apply. Now for real! :)

Thomas

PS: The file to be patched is located in drivers/char/drm/ in the kernel
tree.
