I remember that for high physical address space on i386, readX()/writeX() won't work and that we must get a virtual address from vremap().
Under ALPHA neither the physical address nor the remapped did work.
I understand that now we can use the physical address with all architectures and that will work like a charm. I will try that on my pentium tomorrow.
