Ok, after some playing I have a simple test that show's the label 
background problem.

The dup label problem on a line layer (road names) is not a problem, the 
LABEL_NO_CLIP=1 fixes my problem (or using OpenLayers singleTile).

The dup label problem on my annotate-pin layer is a problem.  The layer 
seems to ignore LABEL_NO_CLIP=1.  If I set OpenLayers to use singleTile 
then it displays correctly.  I have a mapfile with the features defined 
inside (so no perl script is needed).  shp2img displays it correctly 
because, I assume, it draws as one tile.

I also noticed, when drawn as one tile, all the lines (roads n stuff) 
draw correctly, but in OpenLayers with mult-tiles, it get's messed up.

I have a shape file, and a mapfile if anyone wants it, I'd prefer to 
send you the link privately though.
