The last time I looked, this driver was not endian safe.

Thats fine, its due to the way io apertures for different host bridges
are handled. The apertures are mapped in one after the other so that only
the first one has no offset.
If you have more than one host bridge, you have to add the offset since
the io ports are all relative to the start of the first host bridge
