You want the edge.dbfawk, Keith.  Look for the rule lines that begin  
with "/^MTFCC=S"  They are the road rules.  That's where you'll  
adjust the display and label levels to get what you want.  Notice,  
that the values are a power of 2 - e.g. 2, 4, 8, 16, 32, 64, etc.  I  
haven't tried anything other than power-of-2 values.  Someone else  
familiar with the code can explain what might be the consequence of  
any integer value other than power-of-2 values.  Perhaps, it's  
because the default zoom levels, when displaying a map,  are also  
that way.

I'm in digest mode, so you may have already gotten an answer for this  
from others.
