The FBReaderJ¹ used to have the limitation that the HTML files could not be in subdirectories within the EPUB/ZIP file. I am not sure when or if that was solved.
Calibre has some options for EPUB output generation, that include the above deficiency and the HTML file-size limitation mentioned in the question. Other such reader limitations, if widespread, would probably make it as an option to any often used program for EPUB generation.
A far less obvious, but still annoying, limitation is that several readers² do not respect file-as information about the creator/other, thereby sorting correct (western) author names by given name. This in turn made publishers mangle the creators element in their publications with the—for western names—incorrect form "LastName, FirstName (MiddleName/tussenvoegsel)" instead of the correct "FirstName (MiddleName/tussenvoegsel) LastName"³.
The correct way to handle these devices (and the only way if you have multiple devices of which some have this error), is to mangle the EPUB creator element at the time of updating the device, by copying the file-as attribute information to the non-tag part of the <creator> element⁴.
¹ Now called FBReader for Android
² This is a problem e.g. with the SONY PRS-700.
³ For Dutch names the even worse "tussenvoegsel LastName, FirstName" is often used
⁴ You can do this on the fly, as it does not happen that often.
