yes, null alt's allow screenreader to skip over decorative graphics.  by 
the same token, if a standard approach were taken for tables simply 
being used to layout information on a webpage, screenreaders would know 
not to look for/read associative information.  as sailesh also pointed 
out, empty attributes allow for automated testing.  although, in our 
tool, we allow for both empty attributes like summary and alt, as well 
as certain key phrases, like summary="layout", summary="layout table", 
etc..  these values being filled, however, does not help the 
screenreader user.
