one good thing could be to enable the msr kernel module (msr.ko.gz is 
only 2297 bytes with 2.6.x kernel, and 1464 bytes with 2.4.x kernel); 
then we can use flashrom:
http://www.flashrom.org/

here's a binary with kernel mods for both 2.6.x and 2.4.x:

(installer is not yet finished, but should at least work for install)
