A few weeks ago when I thought how cool it would be to marry Wine and Bochs to run Windows progams on Mac OS X & Darwin, I checked around, including this list, and didn't find any activity.
This issue comes up a few times a year (isn't it in a FAQ somewhere?) Anyway, take a look at these threads:

The fact that you're using Bochs does make it unique, but you may still glean some useful info from those links.
