Yes, this is the halacha as I've always understood it.

Crumbs smaller than a kezayis are automatically batel, except "a nice 
rolls", which one would want to keep if one knew about it (e.g. a 
wrapped candy).

There are two reasons why, midrabanan, bitul doesn't help: Lest one find 
a "nice roll", and lest one find chametz and absentmindedly eat it. 
These are obviously related; a dirty crumb that one would never think of 
eating is by definition not a "nice roll" that one would exclude from 
ones bitul.
