A solid state regulator (such as the 7806) has better line and load regulation. At 40 mA it would be dissipating around 1/4 watt... not too bad, and with a couple of tantalum capacitors, it would beat your resistive divider hands down. Of course, it would cost more, but you just can't afford to have voltage fluctuations in a CPU circuit. I don't (yet) have a TWGS, but I think it would be worth the increase in speed to go for a faster 65816. Sure, at some point the increase in speed becomes ridiculous... BUT I WANT RIDICULOUS! Sorry, just wasting bandwidth again..
