amd64 hangs on boot, backing out 181987 fixes it

Hello everyone,
I sync'ed up with HEAD after a long time and now my FreeBSD/amd64
kernel hangs on boot. Backing out this change only (everything else
is current as of 9/9) fixes the problem:
SVN rev 181987 on 2008-08-22 02:14:23Z by jhb
Extend the support for PCI-e memory mapped configuration space access
There have been emails with other problems that may be related:
http://lists.freebsd.org/pipermail/freebsd-current/2008-August/087862.html
http://lists.freebsd.org/pipermail/freebsd-current/2008-August/088072.html
The symptoms that I see are different. My system freezes up
completely - can't break into ddb or do anything else, has to be
power cycled. Backing out 181987 does the trick.
I'd be happy to try out any patches or other suggestions that anyone
may have. Here is the output from "pciconf -lv", "devinfo -r", and
"acpidump -t" from a good kernel. Console output from a verbose
boot with a bad kernel is also provided at the end. If you want
more details, feel free to ask.
Regards,
Navdeep
