I've tried both 0 and 1 for reset_video (but set via sysctl).
And I has 6-CURRENT now, but this notebook never returned from suspend 
(with 5.3 too). It has ATI RADEON chip.

Probably I should try firewire console to detect what happens on resume,
but firewire bus itself should be resumed first. 

Suspend/Resume gurus, is it possible to debug dead console resume with
firewire ?
