Chances are that you've run out of memory.  We had about 5 bytes
remaining after getting the AHRS running, which is why the second servo
bank had to be disabled.  The 20 bytes of position data was just too
much extra...

I setup the link order so that the lcd.o was the last object file.  This
lets the lcd_buf array get corrupted by a stack overflow and let's us
see if we've run out of memory...

Yes, the 2.2 boards will remain software compatible, although the
pinouts might change.  We'll have to have some software remapping of the
inputs and other things so that everything will still work.

The benefits with the 2.4 are the smaller size of the main controller
and the modular IMU.  Depending on your application, that might be
significant.
