Yes, I remember there's a certain restriction on horizontal position of 
some of the sprites.

Glenn, can you define exactly which kind of kernel you need?
Let's try:
Sprites: 4 sprites, single scanline resolution, monochrome, they share the 
same color in pairs. No restrictions on both horizontal and vertical position.
Playfield: blocks, monochrome, non-symmetrical; resolution.. ?x?

I would say that a kernel for a game like this should not be very far from 
the one that Atari did for games like Ms. PacMan or Dig Dug.
Probably you will have to implement "intelligent flicker", i.e. two sprites 
flicker only when they share the same vertical zone.
And I'm almost sure that it's not a simple kernel at all.

As soon as I have found it :)
