Hmm, I think the version in CVS has a few bugs.

Try this one:
  http://snark.ptc.spbu.ru/~uwe/netbsd/jornada/hpcboot13-sh3-2006-01-16.zip

(I hate it that hpcboot needs external proprietary tools to compile,
and so updated in the tree only infrequently.  I can never quite
rememer which of the source level fixes have made it into the
committed binary).

That's a wrong approach.  I've just committed a fix as hd64461video.c
rev 1.36.

Hmm, it was pointed out to me that we have screenblank(1).  But it's
1) broken - it doesn't unblank the screen correctly on keyboard/mouse
activity, and 2) it doens't have one-off non-daemon mode.  This need a
bit more thought.

Strange.  I can only suggest to try some printf-debugging in j6x0tp.c
Does it work better (if slighly off) if you don't calibrate the screen
(tpctl=NO).

That's printed by the WinCE ROM and is standard.
