SiS671 3D Driver Ubuntu 11.04

[javacookies]

I would just like to ask if when I installed ubuntu 11.04 via wubi, driver for my on-board VGA card is installed too?
Or do i have to install what I searched in the net
I also want to use Compiz like the desktop cube but it seems there's no 3d driver available for my chipset.
I know my chipset is OLD but any news onthe 3d driver? Thanks
