They say that it's impossible to change the resolution of the Mobility graphic cards. I hope that maybe somebody will do drivers for these graphic cards.

I've looked at both links, and I thought there is no driver for it yet. That and your resolution are a bit different.

You could try resolution changing for temporary solution while waiting for drivers.
