If they want to approve every change, then just flood 'em with paperwork. 1 day spent automating your process should keep them busy for at least 6 months. Meanwhile you won't have any changes that have been approved, so you can get on with the interesting stuff.
Oh and if anything fails, dies, gets a virus (presumably security updates and virus scanner downloads count as changes) or lets the world and his/her dog steal your company's secrets then it's not your fault: the board hadn't approved the change you submitted weeks ago.
The good thing is that the change board are taking on responsibility for the changes. By approving them, provided you execute them exactly as described, then they are to blame for any problems - as they gave approval. Make sure you keep a paper trail and have a record of everything you do.
They will quickly tire of the burdensome, boring and ultimately futile work. So enjoy the honeymoon period. It wn't last forever, but if you handle it properly, you can shed the blame for any problems for at least a year - even if the board disband. The confusion and lack of clear indications of who should have approved what can be spum out for a long time - in the right hands.
Meantime, you will have plenty of opportunity to look for another job.
