Fixed a bug introoduced in the previous change. ISA device memory was
mapped to semi-random place(s) depending on the content(s) of physical
address 0xA0000. This was fatal at least on my system with a some
memory-mapped devices. Console syscons somehow wasn't affected. It
bogusly hardcodes the address. Sigh.
