my direct response to dan bounced, so i'll respond on the net.

rectwrite was added to the GL when the GT was released.  it was
not ported to the 70G at that time (i think release 3.0).  at
some later release, probably 3.1, it was ported to the 70G.
it is definitely supported on 70G in the 3.3 release, almost
certainly in the 3.2 release.

perhaps someone else knows exactly which release added rectwrite
to the 70G?
