Concerns about the i915 driver

[Kasper Grubbe]

Hello.
I want to buy a laptop with the GMA900 graphic card in it, i read
through some forums and websites that i have to use the i915 driver,
or it is called i810.
Unfortunately i have read that i have to use the xorg cvs to use the
i915 driver, is that correct? And is the DRI modules in the xorg-cvs
so i can enable it when compiled?
And are there 3d acceleration in the driver?

Thanks
