I wasn't going to say anything about this ia64 workaround,
but yes I have to agree with Jeff, this change starts to
lose the whole point of the original change.

Why in the world can a PCI device not handle it's BARs being
rewritten, especially if we're just rewriting the same exact
values it had when we probed it beforehand?

IA64 could handle the necessary cases in it's PCI config space
access methods. Ugly, but keeps the core clean and limits the
avoidance to the cases that really truly cannot handle the BAR
rewrites.
