Gah. That's marked as 2007, but that's an import of a much older
change, and 2.3.49 is way back in the last century.
But I looked at the datasheet for the M1543 PMU, and can confirm that
there's nothing at e0/e2 according to that datasheet. The PMU IO bases
show up at 0x10, and the SMB IO base at 0x14 in that doc..
Those kinds of things sometimes change between revisions, and it's
possible that there were versions that had them at that e0/e2 area,
and it got moved to the standard PCI BAR locations later.
I was definitely involved in these things, but my memory just doesn't
go back far enough to haev a clue what is going on. The only one I
remember working on myself was the PIIX4 one.
Removing it based on current datasheets and a failure of a known sparc
setup sounds reasonable.
