That wouldn't work with the filesystem used (vfat). Any file or folder you create there is chmod'ed to 0777, and trying to change that by chmod yourself yields no change. I think I read somewhere here, someone suggested at some point reformatting that partition or part of the internal storage to ext3 so you can get more fine-grained control over permissions on the exported internal storage, but that's a big change on the underlying system with a lot of room for causing operation problems with the Kindle UI and its inner workings in general. And if we're talking about meddling with partition formatting, then we're talking about only rooted devices, which throws out the window the only advantage the dummy file/folder hack has over disabling the OTA service, which is that it work(ed) on non-rooted devices.
