Confirming. With 2.6.33, I don't get the warnings, but neither get the
procfs-entries.
Checking my debug-output again, I assume that the hard-disk has the entries,
because it is the first user of ide-gd, so that driver still needs to be
requested. Maybe this is enough delay for the directories to appear? Wild
guess...
