Userconfig has brokeness in this area. Specifying -1 will result in shifting the bit all the way off the end, resulting in "0". There is supposed to be a difference between 0 and -1. 0 is supposed to mean "none" and -1 is supposed to mean "auto". Apparantly all the drivers must treat 0 and -1 as the same. -DG
