Then, inb(0) converted to physical address 0x10000000
(GT_DEF_PCI0_IO_BASE), and on PCI bus it is PCI IO address 0? or

If PCI IO address was 0, io_offset should be 0.  Otherwise, io_offset
should be -0x10000000, as current code does.

So if it does not work now, something's going wrong... but I have no
idea now.
