I think this is an ACPI problem.  You can load a modified DSDT at
boot.  No need to replace the BIOS.  There are very few laptops
supported in coreboot right now because the embedded controllers are
not documented.

flashrom reads and writes the flash chip that contains your BIOS.

Your board isn't supported by flashrom yet.

I think it would be easier to get ACPI debugging tools and modify your
DSDT.  This isn't the list for that, but here are a couple of links.

Google for more ;)
