I just wanted to say thank you for everyone on the thread who spend their time to make my life easier. Special thanks to Sloth(your howto and igd.c was very useful) and angri(for mentioning lvds_use_ssc=0 option that helped me to deal with green screen issue). It took me some time but now I have a mbp 8,2 with radeon graphics switched off and suspend/resume working like a charm.
For those who can edit https://help.ubuntu.com/community/MacBookPro8-1/Natty , please add a direct links to the http://ubuntuforums.org/showpost.php...&postcount=259 (Sloth's howto), http://ubuntuforums.org/showpost.php...&postcount=261 (igd.c for suspend/resume) and http://ubuntuforums.org/showpost.php...&postcount=593 (green issue). It will save a lot of time for anyone who wants to put linux on their mbp.
