So with regular cheap tape you cover this pin so it is always "on". I dont know for sure, but do try using tape to cover both sides. Boot into windows to check it is recognized and that the button does nothing.

When you succeed, boot into OSx and it should recognize. And be sure that you install the BCM41xx kext - this can be done by loading up iAtkos 7 install, unchecking EVERYTHING and just select the broadcom wireless driver.

When it is done, it sould reboot by itself. Sometimes, after installing the kext, right before rebooting, there can be a exclamation mark in yellow giving some "error" - just ignore this and reboot.

To be more precise, on reboot flag it with -f flag to rebuild cache, but its not mandatory

Also, if varnish IS non-conductive, you can very easily spill onto the next pin. How can you be that precise in covering just that pin with varnish?!?! The difficulty with tape is just cutting that a small piece, can't imagine with varnish...
