Jari Oksanen and Pierre Legendre have been working on a Model II regression package/functions. These will be added to the Vegan R-Forge repository real soon now. If you don't get any other suggestions, then perhaps you could contact Jari directly to enquire about the code if "real soon now" is not soon enough for you. Vegan details are here: http://r-forge.r-project.org/projects/vegan/ Where you can get Jari's email address as well.
