I file that under "hiding bugs", since it will not be immediately obvious to a bug hunter or maintainer what the real problem is. If a driver is broken on 64-bit, please add "&& !64BIT" to the Kconfig. As you yourself just explained, your wish is to use CONFIG_ISA, but your intent is only coincedentally related to ISA. Jeff
