Thanks a lot for the tip! That gives:

      pass: 172
       fail: 15
      crash: 909
       skip: 1
    timeout: 0
       warn: 0
 dmesg-warn: 0
 dmesg-fail: 0
      total: 1097


which correlates well with the fact that there are a lot of things simply
still missing. I've been mostly playing with uniform support so far. The
reason I sent the work to the list is to check if people agree on the
basic design choices.
