      Apologies if this message shows up twice, I may have sent it from the
      wrong account the first time...


      Here's the sequence :

      # insmod usbserial.o
      Using usbserial.o
      # insmod keyspan.o
      Using keyspan.o
      # lsmod
      Module Size Used by Tainted: P
      keyspan 109492 0 (unused)
      usbserial 19528 0 [keyspan]
      x1226-rtc 3664 0
      pbuttons 800 0 (unused)
      rbuttons 1304 0 (unused)
      ixp425_eth 17116 1
      ixp400 608216 0 [ixp425_eth]

      So far so good. Then I plug the adaptor in, the virtual address of 0 is
      the same each time I do this and, I think, for all oops/devices :

      # dmesg
      ...
