SiS based graphic card and OpenSUSE 11.1

Has somebody tried to (compile and) install SiS graphics driver on OpenSUSE?
I found this page:

SiS on Linux: Front Page

Any info about using this kind of hardware with OpenSUSE would be appreciated.
At this moment, a relative of mine is using a laptop with this graphic chipset.
After installing OpenSUSE 11.1 I noticed that it uses the Vesa-driver.
As a result, the graphic performance is horribly slow.
Watching avi’s in kaffeine is only possible in a small window. Full screen isn’t possible.
I don’t need 3D support but some 2D acceleration would be nice.
