That's the simple mod with some photos showing the principle at
http://stuge.se/m57sli/
A variation to the concept is to have a switch pull down the HOLD#
pin to GND. This should also work fine as long as the switch is not
toggled while the flash chip is being accessed.

I guess whoever made the PCB can publish source and gerbers so that
others can order the same board if they want.
