You know nothing about that the fact that PCI_Config space have
to be accessed as 32-bit reads/write. It may be the
Field(PIUC, DWordAcc,...) to be bogus. A better look of this field
is needed.

Imagine it look like
Field(PIUC, DWordAcc, ...)
{
FOO, 16
}

then a better fix is:
OperationRegion (PIUC, PCI_Config, 0x74, 0x02)
Field(PIUC, WordAcc, ...)
{
FOO, 16
}

Or FOO may be 8 bit long.
In that case, a possible fix is:
OperationRegion (PIUC, PCI_Config, 0x74, 0x01)
Field(PIUC, ByteAcc, ...)
{
FOO, 8
}

Unless sjb give us more info, we can not tell anything at this
stage.
