I have seen Coreboot running and I am pondering to load it on several boxes here - as soon as I get some exhange BIOS chips flashed with the original BIOS. Just in case.
It's sad to read that some mainboard people still provide buggy firmware be it classic BIOS, EFI and stuff. Bad ACPI implementations and defective by design "secure boot". Anyway, Coreboot has a long way behind and there is still way to go. I think we'll need some patience here until coreboot, flashrom and potential payloads like SeaBIOS work everywhere.
Stop TCPA, stupid software patents and corrupt politicians!
