You are telling me I have to use four different programs and spent several hours before I can actually read "problematic" PDFs ...
So this seems to be for people with a lot of patience and a complete disregard of time.
ScanTailor postprocessing (usually takes about 30 minutes on modern computers depending on the size of the book, the resolution of the images and the processing power) improves the formatting of scanned books and they look better regardless of the device. It also happens to make the book readable on Onyx M92.
If you don't care about the formatting and still want to read it on your M92, just download the djvu file from archive.org. You can read it out of the box without additional tampering.
I am not telling you that you have to do anything. I am sharing my experience, in case that someone finds it helpful.
