  ok, i guess i can try another display.  curiously, i've connected
the same display to the output of my beagleboard, and the splash
screen of the u-boot bootloader shows up crisp and solid.  and stays
there.

p.s.  the beagle board (beagleboard.org) has an HDMI-format output
*connector*, but outputs only DVI-D.  i was simply pointing out that
*that* signal has no trouble on that display.
