Hi Warner,

I experienced the following with this patch:

*) I still need to set hw.pci.allow_unsupported_io_range="1", otherwise
   cbb0 wouldn't attach:

cbb0: <TI1520 PCI-CardBus Bridge> mem 0xb0000000-0xb0000fff irq 4 at
device 0.0 on pci2
cbb0: Could not map register memory
device_probe_and_attach: cbb0 attach returned 12
cbb0: <TI1520 PCI-CardBus Bridge> mem 0xb1000000-0xb1000fff irq 5 at
device 0.1 on pci2
cbb0: Could not map register memory
device_probe_and_attach: cbb0 attach returned 12

*) My UHCI controller finally survives suspend/resume - YAY! :-)  But
   there is still something bogus with EHCI:

   *) boot - kldload usb -> ehci0 fails to attach.
   *) boot - suspend/resume - kldload usb -> ehci0 attaches successfully

   Failing looks like this:

*) I'm seeing some "Failed to set ACPI power state" on boot, dmesg is
   attached.

*) Otherwise, everything seems fine.
