There's a new post today on the dpreview Pentax DSLR forum that mentions banding; it shows up, for this particular case, when shooting at high ISO in continuus exposure (machine-gun) mode. The give-away is that the banding never shows up on the first shot of a burst, just on later shots (when writing to the CF card happens at the same time as a subsuquent exposure).
