Thank you so much!
My conf of Dell Inspirion N7110: i5-2430m, HD3000 without any discrette graphics, 4Gb Ram (2+2) PC-12800, Wi-Fi N1703 with BT on Atheros 9285 (I guess) in stock.
It was not easy to use your guide, but I don't give up. Now I have native resolution. This is first time (!) when I get it.
Now I'm testing system. But I have some troubles with booting. Offen I have KP. But if I boot, seems working.
Sorry for my poor English)
