Borates are great and I plan on lining the attic with it, but still the Formaldehyde concerns me... along with a few other considerations... here is a "green site" that discusses it:
http://www.greenbuilder.com/sourcebook/Insulation.html
"Cellulose insulation uses recycled newsprint that contains printers inks which can possibly outgas formaldehyde into a home. If there is any outgassing from inks, it should fall well below levels irritating most persons. However, an environmentally-sensitive person should be careful in selecting cellulose and install a vapor retarder between the insulation and the living space. (Note that the vapor retarder can exacerbate mildew problems if humidity levels in the house are high.)"
