They are supported, but when a polygon is not labelled,
v.to.rast doesn't produce any cell. If you label them
with v.digit, you will see all polygons.

When its job is finished, v.support display something like :
 Number of lines:   6092
 Number of nodes:   4147
 Number of areas:   1946
 Number of isles:   1
 Number of atts :   466
 Number of unattached atts :   5

That means that only 466 polygons are labelled, so you
will not see the 1500 others on the raster produced by
v.rast (this can be right if they are holes in other
polygons)
You see also that 5 labels are not inside a closed polygon.

No... (I'm working on it, but slooooooowly)
