The traditional legacy ISA devices -- floppy, serial, parallel, mouse, keyboard, IDE -- are still around. Yet now we need to invent a new name to classify ISA devices that have been with us for 20 years?
CONFIG_ISA_BROKEN is more appropriate than pretending devices we've called ISA since the 1980's do not imply/depend on CONFIG_ISA.
