Hibernate/Sleep and Mic issue for Sony Vaio sz220?

[Yetties]

I installed iatkos v7 (10.5.7) on Sony Vaio sz220 with GMA950.
Everything works fine except Hibernate/Sleep and Mic.

I use default setting in iatkos v7 with Chameleon 2.0
After installed, the screen goes dark when I close the lid, and the fan doesn't stop. (don't work by clicking sleep from menu, either)
I saw some threads talking about DTST and PC EFI.
Is Hibernate/Sleep related with DTST or PC EFI?
Does anyone have any clue or kind to tell me where is the guideline?
I tried to seach the forum, but didn't find a clear guideline for Hibernate/Sleep.

Besides, the internal mic on front panel and line in both don't work.
Is there any solution for front panel mic to work on notebook?
I tried some AppleHDA files, but none works.

Please help, I tried to make it work for 1 week.
I would really appreciate even if just a little clue.
Thanks.
