Hi Matt,

Problem (kind of solved), that computer was kaput, it's already waiting 
for the UPS pick-up to the Acer Repair Center (luckily that unit is 
still in warranty).

I have another identical netboot, which I just installed 9.1-RELEASE 
on. CPU fan behaves normally, shutdown and reboot is working now, 
suspend/resume is working except no video on resume.

Greetings,
