Partial kernel.log

Here is a partial kernel.log tracking what is going on at boot with some debug
printk in evergreen_mc_stop() and evergreen_mc_resume(). Strangely, only one
crtc is saved as enabled in the _stop function, but four are restored in the
_resume function. Pretty sure it's not the problem we are looking for, but it
is abnormal since only one crtc should be restored on resume. This is a bug by
itself showing a problem in the save(stop)/restore(resume) mechanism.
