Apologies for this. I built those packages, and haven't got around to
updating the README. I will try and do so tonight.

i686 and x86_64 are the 32 and 64 bit versions respectively. The names
come from the names for these platforms used in ./configure. Probably
not something that I should be inflicting on users. The "deps" package
are the external dependencies that Emacs uses, for features like XML
parsing, image rendering and so forth. If you unpack these over the
relevant version of Emacs, it's powers will be magically enhanced.
