Quoth Dr. Frankesteen: "It's alive!". Helge's oneliner in shced.h did
the trick. After patching in a custom DSDT, this is my leftover list
of things that go boom on recent kernels:

* During shutdown, whilst stopping hotplug and unloading usb hub
  drivers, machine freezes hard. Last printout is something along
  these lines:

        "usb-ohci 02:0e.2, address 3", or some such.

  Then the machine becomes a doorstop.

* Synaptics touchpad driver as of 2.5.69 does not recognise the "tap
  to click" functionality, and doesn't seem parse it's boot param to
  enable it, I get it to work by hardcoding the PARM-line in
  driver/input/mouse/psmouse.c to a "1". This might very well boil
  down to user error (PEBKAC) on the boot time parm, but the auto
  detection that worked up to .69 is b0rken.

* Insertion of my Palm cradle in the USB ports will result in this one
  once the cradle tries to go active (this one is from -mm2, present
  in -mm3 too):

* On -mm3 under some loads mplayer can get very erratic, and after
  playing a videostream for about 10-15 mins it gets progressivly more
  prone to stalling. Moving the mousepointer into the window, and wiggling
  it a bit restores it for a while.
