Size is relevant because a kezayis is chashuv, and therefore not 
automatically batel, whereas a crumb smaller than that has no value, and 
is thus as if it doesn't exist, unless one specifically values it.  Even 
a "nice roll" is batel unless one finds it and thinks about keeping it, 
which gives it value and thus takes it out of that category.

We see this not only on Pesach but also with regard to the respect one 
must give bread; crumbs under a kezayis don't count, and one may throw 
them away, needn't pick them up off the ground, etc.

But only for crumbs bigger than a kezayis.
