I think the advantage to series diodes is that they provide nearly the 
same voltage drop (~.6v/diode) no matter the current (within limits). 
This can somewhat relieve thermal stress on the regulator at lower 
currents compared with a simple resistor. The diodes still need to be 
able to dissipate the same power as a resistor would at maximum current 
and *more* power than the same resistor would at lower currents.
