Now I have. I am not sure how to interpret it, though. Running showttf
on Junicode-Regular.ttf gives me:

         Language System table for 'ISL '
          LookupOrder=0
          Required Feature Index=0
          Feature Count=0
[...]
        Feature List
         feature count=15
         Feature[0] ' RQD' Offset=92

This looks ok, but I am no expert on the internal of OpenType. XeTeX
does not like this. I have added a normal feature to latn{ISL} so that
it looks like this:

         Language System table for 'ISL '
          LookupOrder=0
          Required Feature Index=0
          Feature Count=1
           Feature 0 Offset=12

Now XeTeX applies the required feature when Icelandic is selected.

Looks like a bug in XeTeX/ICU, right?
