PCI I/O region is 0x3f800000 bytes starting at 0x80000000.
Do not use global QEMU I/O region, which is only 64KB.

With this patch I get only a blank screen in OHW/Etch.
There seems to be conflict with the PCI I/O region added by this patch with the
memory region registered by PReP machine to handle non-contiguous I/O.
Attached patch fixes it, but it may break non-contiguous I/O up to patch 08/10
(I've no mean to test it)
Another possibility is to merge patches 05 and 08 into one, as 06/10 and 07/10
can be freely reordered.
