The two really aren't mutually exclusive.  Besides, fdt_checkboard() would not work in a 
hush script.  The C function would scan the device tree *and* read data from the hardware 
and compare the two.  For instance, if it says that there's a PCI device at address X, it 
should check if CFG_PCI1_MEM_PHYS is set to the same value.  These are the kinds of things 
that can only be done in C code.
