Lack of time and too many tasks. :/ I've flashed Coreboot on a desktop motherboard, where there is one advantage - the flash chip can be replaced (in some cases).
Basically, Coreboot has a sister project which is a general purpose flash (&& EEPROM) chip programmer. You have to use it to install Coreboot. It communicates with the flash/BIOS chip over a system bus from GNU/Linux. The procedure describes how to change flashrom source code to work-around the proprietary BIOS restrictions which prevents BIOS flashing on the entire chip. It seems the modification is flash chip specific. The proprietary BIOS is read from the chip for backup (recovery if necessary). The Coreboot image is prepared and the flash chip is programmed with the special image. When Coreboot is flashed and the laptop boots, the entire chip is reprogrammed. This procedure uses the internal system bus for programming. If an external programmer and a SO-8 IC clip mentioned in the recovery section is used, the modifications should not be needed. The external programmer approach is more complicated. If you need more help, I would be glad to help. You can also find me on the Trisquel IRC channel as thedreamer. I'm usually online most of the time (UTC+2:00), but during work hours I'm at work, (duh! :)) so I won't be able to spare more than 10 minutes.
