No problemo, I kind of vanished off the face of the earth after my last
mention of releasing a 2.5 patch, which was over a month and a half ago.
Now that we've got our new hardware platform up and running here at SOMA,
I'm back in a position to work on hotplug stuff again.

I think Ivan's new code in setup-bus.c (pbus_size_bridges and friends)
removes the need for a pci_write_bridge_bases and my code to update the
bridge resource windows. I hope so, since I've changed my driver to use

I hopefully will have something working against 2.5.44 tomorrow. I think
the only potentially contentious piece that I'd like to get reviewed and
maybe integrated before the feature freeze is the resource reservation
stuff. There seemed to be no serious objections to the 2.4.x version I
posted a while back, so maybe this won't be a big deal. Everything else
is either __devinit/export tweaks or driver code.
