Fixed the kernel and did some more testing, and I think I've figured it
out.  It appears that the actual start pixel for the ball is at RESBL + 4
pixels.  So if I want to position the ball starting at onscreen pixel 2, I
have to hit RESBL at CPU clock (68 + 2 - 4) / 3 = 22.   (Which, of course,
wrecks my nifty 8 cycle timing loop.  Sigh.  But it looks like it was off
anyway...)

Or have I got it wrong entirely?
