Actually my test program corrects the baud rate based on what it thinks the 
CPU frequency is, so since I can still receive the output and it prints 
that it thinks the internal rate is 30MHz....

Hmm, I should be able to fool the timer by setting the cpu clock after it 
inits....

That's a little more definitive.  Start up timer with cpu frequency at 
10MHz, then switch CPU freq to 30MHz and use timer to toggle output pin 
every '1 sec'.  Measure high time

High time = 333ms

IE internal clock is 3X what it was when timer was started.

Looks good to me.
