Sounds like the right direction to me.  There is a PC Magazine
utility (DIMMER) which might provide some additional information
about the interrupt handlers if you need it, even though the
screen blanking routine itself is VGA specific.  The source is
assembly.  I can mail the source if you like.  Lemme know.
