Can't that be avoided by setting ISA_SEX/isa_sex appropriately?
i tried ISA_SEX to do the be->le flipping but it broke all drivers: it seems
like isa_insw()/isa_outsw()/isa_insl()/isa_outsl() must retain the host
endianess.
Oh, I missed you're only overriding the non-repeating variants.
So ISA I/O registers are little endian, while ISA FIFO registers are
native endian, as they operate on the raw data stored somewhere else
(network, disk, ...)?
