PLCC (the physical package) support different protocols, cf.
http://flashrom.org/Technology#Communication_bus_protocol
The W39V040FC is a FWH chip and thus could in theory be accessed with a
RaspberryPi - it has enough GPIO ports. I am not sure if they can be
toggled fast enough, but I'd guess so. The problem is rather to write
the respective software/driver - AFAIK there is none yet.

It would definitely be easier to get a similar board and try
hotswapping the flash chip.

Yeah, I think I'll just go the hotswapping route for the moment. I
just haven't been tracking Flashrom for a while now :-). Thanks for
the info.
