Hi Martin!

Thank you for your work/findings, this works for me on Asus N82Jv! It's the
first time I can use the nVidia card! :)

For now the major problems I face are the loss of transparency (why?) on
icons, for example, and the 3D acceleration due to the mesa libraries.

00:02.0 VGA compatible controller: Intel Corporation Core Processor
Integrated Graphics Controller (rev 18)
01:00.0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT
335M] (rev a2)
