Doh, apologies for the specific query thing. I need caffeine.
I see the same for several other queries - mostly for brands whose names may also be generic terms. (As it is a specific brand I've edited out the query I quoted above).
Not sure how much the brand/generic ambiguity plays a part is at all, but certainly every example I've seen is an exact domain match that brings up sitelinks.
In other words, if your search term is a domain match and the domain's result displays sitelinks, then only 7 results are shown.
