 % no.  it happens with every screen saver, right after kldloading it.

 % timeout defaults to zero, but in that case screen saver should be disabled.

 %
 % yes.  the problem, however, is that screen savers blank the screen
 % right after being kldloaded.  i load it from /boot/loader.conf, so it
 % blanks the screen somewhere during kernel initialization, before boot
 % scripts can set blanktime.
