Thanks. The patch probably fixes it on x86, but it's still the wrong thing to do (you really _have_ to use readb/writeb to be portable, because accessing IO memory is not just a matter of getting the right address, on some architectures you have to do special IO cycles or coherency stuff instead of just a pointer dereference).

Ok, good to know that I didn't do anything overly stupid with the system call entry point optimization etc.. Btw, has anybody tested whether "dosemu" still works in pre-2.1.0?
Anyway, wrt the aha152x driver: could you try the _newest_ pre-patch (currently #4) to see if the aha152x driver works with my version of your fix too? I've written the code to do it portably, but I obviously cannot test if it actually works..
