-kernreg- is a user-written command published 
in 1996. Thus it could not have been written 
to be compatible with the new graphics of 
Stata 8 released in 2003. The same 
applies to later versions by other authors with 
fewer bugs. (A corrected version of -kernreg- was never
released by its original authors.) 

However, all that is now historical detail, 
and other versions of -kernreg- would leave
you with the same graphics problem. 

I guess that you would be much better off 
using -locpoly-. 

. search locpoly 

will identify the source, and something like 

. locpoly mpg weight , <options> 
	plot(lfit mpg weight, <options>) 

should do what you want.
