While it does not support all current x86 chipsets, it still does support quite a few mainboards. The developers are friendly and try to fix any reported bugs. There are two big obstacles until x86 world domination, though: A dozen core developers are simply not enough for the huge task (there are more open specs than developers can keep up with), and some chipset vendors don't open their specs. Anyone interested is invited to contribute and make the world a better place. Oh, and it supports packing a Linux kernel in the mainboard flash ROM for diskless/networkless booting (that coreboot+Linux combination was called LinuxBIOS some time ago).
