Thanks, that took care of it.  But now I've got
another question.  What is the down side of using the
vesa driver.  The reason I ask is because keeping
XSERVER=auto, and setting X_COLOR_DEPTH=15 gives me
worse looking graphics than XSERVER=vesa and leaving
X_COLOR_DEPTH alone.  Is vesa bad at motion?
