Here's the answer for anyone else with this problem. This was from Shine On, who provided this very simple solution for me:
I just put Verbhelper.kext in /Extra and ran update extra. Kext helper inst necessary for any kext additions done on the minis and there's less risk of complications using the /Extra directory.
I did uninstall sleepwatcher after I installed Verbhelper.kext, but I ended up reinstalling because sound would work about 90% of the time after sleep, but still would, on occasion, disappear after sleep.
