This message thread elsewhere seems to suggest that there's a possibility of needed 24-bit addressing on? Does that make any sense?

Also (http://www.vectronicsappleworld.com/appleii/appleiiecard.html),

The Apple IIe Card originally shipped before System 7. The Apple IIe Card Owner's Guide for the Macintosh LC, copyright 1991, Apple Inc., advises against using the card with System 7. Furthermore, the guide states that the Apple IIe Card was tested only with version 6.0.8 of Macintosh system software. The guide suggests that if you use the card with System 7, you should have at least 4 MB of RAM and file sharing should be turned off. We use a Macintosh LC III with Mac OS 7.5.5 and have not noted any issues. We have IIe Installer Disk, Version 2.0, released in 1991. The final version is 2.2.1, released in 1993. The final version is compatible with System 7 up to Mac OS 7.5.5. From Mac OS 7.6 onwards, Macintosh system software does not support 24-bit addressing and thus is not compatible with the Apple IIe Card.

Maybe you should try 2.2.1 (if you haven't alread), since the information for the 2.2.2 file (http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English-North_American/Apple_II/For_Macintosh/IIe_Startup_2.2.2d1_Info.txt) says that that version is for LC/Performa 575s and you say you have a LC 475.

I'll just tack this on: http://www.vintagemacworld.com/lc_card_faq.html (I'm guessing you might have read that).
