dwmw2 has been told repeatedly that his changes will cause PRECISELY 
these problems, but he refuses to take the simple steps necessary to 
ensure people can continue to boot their kernels after his changes go in.

Presently his tg3 changes have been nak'd, in part, because of this 
obviously, forseeable, work-around-able breakage.
