I have. kernel from just crashes on my device, (MTD in or not),
and I have no time to investigate this issue, so I keep to 2.6.7 (no

state, but some of the API seems to have changed.

Whoops, didn't pay attention to this :(

Is there some means to determine chip type by software ?
Things I can read on the chip (hoping i'm correct, it is not very
readable) are:
