Doesn't matter.  Drivers are allowed to [1] call ioremap() on ISA memory
and then call readb() on it.  You need to figure out how to handle this
on m68k.  Since I'm not familiar with the architectures you deal with,
could you go over the problem you have?

[1] and encouraged to -- isa_readb() is legacy and being phased out!

conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain
