For what it's worth, the 64 disk routines distinguish between a load
and a verify; the main routine ($F7xx or so I think -- going from memory
here) runs something like

	LDY verify flag
	LDY #00
	CMP ($AE),Y
	JMP ERROR	;...something like this

so loading stuff into the ROM area is no problem.

Just a little trivia :).
