 It took some time to rebuild HEADs tool and GENERIC kernel from
 scratch on my cubietruck (!).
 Compared to
 my GENERIC kernel is about 400 kb larger:
   tar tvzf kern-GENERIC.tgz.1 | grep netbsd.ub
   -rw-r--r--  1 root     wheel    8473324 Nov 21 10:49 ./netbsd.ub
   rw-r--r--  1 root  wheel  8939436 Nov 21 20:33
 Does that mean anything, yet?

 I don't know, but I can trigger maybe another (real) problem with that change.

 'netbsd.ub's size does not change with and w/o this change.
  Also, does the problem occur with VERBOSE_INIT_ARM/EARLYCONS defined?
 I can test that later (tomorrow?) ...

 SUNXI kernels panic / stuck suddenly, so I switch over to GENERIC kernel.
 If it helps I can build an actual SUNXI kernel and try again.
