Thank you so much for testing!! I didn't find ich7 device... you helped me so much!

PS2: 
New patcheset is a result of merging with commit 93b01904db607ef8169047e68e376dcda1bd7fbe and fixing some comments. But I want to test it again, at least the init_ich_default path that I can test, to verify that I merged correctly with commit 93b01904db607ef8169047e68e376dcda1bd7fbe. I plan to do this tomorrow and then once it's ready I will resolve all comments.
