Poss the banding can be corrected by anisotropic filtering settings? Just checked on my sys and I don't get them... hmm... but I have filtering set to off, hmmm, but I have Force Mipmaps = bilinear, so maybe that's it? Anyway, this is a 600MHz PIII GF2 MX, giving ~60fps.
PS: Nice demo lee. Only problem I see, and it's in your gfx above, is mismatched texturing.
