Yesterday evening i tested writing to flash with flashrom. Albeit still only 
with the original firmware blobs in different versions to verify that s.t. 
had changed.

I tested writing to both chips and switching chips while running. Thus i 
verified that:
* only one chip is written at a time,
* both chips are writeable,
* it is possible to switch the flash-rom's while running.

So i think everything except the question about the direct ground pulldown of 
the INIT# pins (with or without resistor) is clear that it works as expected.

Concerning the pulldown: I currently have only a jumper connected to the 
chips, this makes switching somehow delicate since it takes some time pull 
the jumper of and put it on the other location. In this time both chips are 
active, which is not to nice, but i can report that it works nevertheless. I 
had some suggestions to put some resistors in between the switch and the T12 
and T22 pins.

I also tried to build linuxbios with a linux payload, but somehow the kernel 
bzImage was way to big to fit into the flash. Is it possible to fit a 2.6.2x 
kernel into 4MBit flash-rom?
