I have tested Intel adapter. And test results shows problem with brightness 
control. Brightness level stop changing after loading kernel. Another problem 
I found is that laptop just hang during shutdown. I suppose that hang may be 
related to VT switch, because it still dont realized in case of Intel KMS 
driver.

USB works fine. For example suspend/resume passed fine when USB flash dive 
inserted. And after resume I can access files on that volume.

I found only one problem: If at suspend time I have running VM Windows XP then 
resume process will fail.
