o Delete pcic1 from NEWCARD o Add explicit resource hints to pcic0 o Get attach working with newbus, kinda (it does all the newbus stuff, but doesn't try to attach the pccard yet, too many panics). o Disable ie0 and le0 in NEWCARD config. There appears to be a bug in the isa_compat code wrt memory conflicts with newbus drivers for reasons unknown. o Minor cleanups.
