I tried out 8.2-STABLE (from Feb 3rd) on my IBM Thinkpad X40 to see
whether the updates to usb fixed the resume stall problem with
8.2-RELEASE.  (The latter with the "gavin-usb-controller-patch" however
worked very well on this system!)

Unfortunately, 8.2-STABLE didn't improve.  On the contrary, no usb
devices at all work after resume, so this is kind of a regression.  I
tested with a couple of different versions of the usb system and
concluded that it is commit r229370 that makes the difference.

After resume, the console says:

uhub1: at usbus1, port 1, addr 1 (disconnected)
uhub2: at usbus2, port 1, addr 1 (disconnected)
uhub3: at usbus3, port 1, addr 1 (disconnected)
uhub0: at usbus0, port 1, addr 1 (disconnected)

What can I do to debug this further?  It would be great to be able to
sort this for 8.3.

The laptop (Pentium-M CPU) has these usb controllers:
