If cutting a pin is needed, why not the CS pin? Much neater IMHO. Of course you still have to solder a resistor between this pin and the +5V pin.

Seen from a technical point of view I never liked the method of disabling an IC by powering it down. I know it works, the 6502 in the SuperPET is the living proof. But one day you replace the IC with an 'equivalent' IC and then you wonder why the system starts to hick-up once every few days.
