Really old or inflexible programs might need to be run in Compatibility Mode for older Windows versions, but the only ones I have ever had to do that with are games that were initially coded for XP and never patched/updated to support Vista properly.
I think things are getting mixed up a bit here. There are two pieces to the puzzle.

1) The Reader Library Application
2) The Sony Reader Kernel Extension (device driver).

In terms of item #1, the application, Mac OS X behaves similarly to Windows: it runs 32 bit apps just fine when booted in 64 mode (in a twist, it also runs 64 bit apps when booted in 32 bit mode). So the Reader Library Application runs, no problem, all (most) systems go, regardless of 32 or 64 bit boot.

However, the problem is item #2, Sony's separate Kernel extension that installs at the same time as the Reader Library Application. It is 32 bit only and means the 64 bit booted OS cannot run it because anything in the Kernel must match (32 extension for 32 bit OS, 64 bit extension for 64 bit OS).

Without this Kernel Extension, the Reader Library Application will not communicate with your Reader. The Application will do everything else, like display books, let you make purchases, handle downloads, etc., but it will not copy to your Reader (hence "most" systems go).

So, in short, the Reader Library Application runs fine regardless of OS mode. It's the Kernel Extension that depends on the OS mode.
