That depends a lot on the embedded controller in your laptop. Unfortunately, finding the embedded controller chip by software is next to impossible because almost all embedded controller data sheets are under NDA or totally unavailable.
I've been having a hit rate of 100% on free data sheets for the ECs used in 945 based systems so far. Doesn't significantly help though, as the protocol for communication between "the bios" and the EC firmware is usually not documented, and schematics for the systems are hard to find.
Daniel, you might want to start with reading out your flash chip with flashrom, finding out what chip it is, open the laptop, check if it's socketed... Find out what superios are in there (superiotool), investigate the system with inteltool, ...
