By the way, for pluggable ISA devices (like NE2000_ISA or WDT_IB700), it
would be great to have a ISA_DEVICES config switch, just like the
"PCI_DEVICES" switch, which the ISA devices should then depend on
instead of "ISA_BUS". Then it would be easier for the users to disable
optional devices in their builds.
