Did you remap memory to put the bootloader back at address 0, or 
something else? Only thing I would be concerned about is if Philips 
changed the bootloader so that it reset the iodir on P0.14.

It would be nice if Philips provided a reliable (as in supported) 
mechanism to get back into the bootloader from user code.
