I Need Driver GMA 3100 (not GMA X3100)

I use Leopard 10.5.0 . I Need Driver GMA 3100 (not GMA X3100)
Help me!! Please.....:spinme

Apparently there is no driver for GMA 3100 yet.
The most complete thread i found on this card is here:
and it does not look very promising yet.
Note that GMA 3100 has a different chipset than GMA X3100( which is working)
