Update. Not all ship-shape. I still see the linkss folder, but my Kindle is using the stock screensavers. Un-installing and re-installing the hack now.
[editing this post rather than being That Girl who keeps posting]
I uninstalled the hack. Still saw the linkss folders when plugged in via USB. Still dropped the screensavers install bin, and successfully installed the hack, seeing the "checking for screensavers" dialog. BAZINGA. Back to custom screens. Whew!
Just wanted to leave this here for others who may have similar confusion.
