Sure, the overclocking/overvolting is a hardware mod, plus a frequency change in the cgminer startup line
sudo /usr/bin/screen -dmS cgminer /opt/minepeon/bin/cgminer --scrypt --no-submit-stale --gridseed-options=baud=115200,freq=
950
I've been running Scripta since I received my miners. There was one incident when the devices were not showing and I had to reboot, but it has been solid for me the rest of the time.
Does the overvolting work with wheezy too?
