 ok, i thought about this, and i reckon that it'd be ok to do this:

 * use the USB-OTG "boost mode" to provide USB-OTG power to the EOMA68
CPU Card [only]
 * put the SYS-V output through to the main PCB1, where it will do
boost conversion to 5.0V for USB ICs.  SYS-V output could go directly
into the step-up converter for the LCD backlight, and also directly
into the 3.3v regulator.

 so... the spec doesn't change, just the implementation of PCB1.
