That sounds unlikely. Flashrom definately should _not_ turn off your

No AMIC chip is currently supported by flashrom. There's a datasheet, so
it probably can be done. Someone needs a test system, though.

The chipset is not yet supported, but it's probably doable.
Nobody has ever run LinuxBIOS on any laptop, though, see
http://www.linuxbios.org/Laptop. I would not recommend trying it, unless
you really know what you're doing.
It would be nice if you could post as much information as possible to
the mailing list, so that we can add it to
http://www.linuxbios.org/Laptop_survey. It's definately on our todo
list to support one or more laptops...

Shouldn't be too much work, really. The problem you have is that you
don't want to test this on your laptop. Your BIOS chip could be soldered
on, and/or you might not want to open your laptop (warranty). So if
something goes wrong you'll end up with a pretty useless, broken laptop.

There are probably some methods to read, but when it comes to writing I
would be very careful if this is a laptop (see above for reasons).
