We just discussed this on IRC. Go ahead and generate a patch to
unconditionally turn on DBCR0[IDM] in head_44x.S. Don't even bother
wrapping it in an #ifdef CONFIG_somthing block. It should be safe,
but we'll throw it into -next and see if anyone complains. If it does
cause problems, then it can be reworked to something a wee bit more
