Did you change something?
OK, more information on this. If CONFIG_DEBUG_SERIAL is set to 0, the bug is gone (i.e. grub serial works as expected), but sgabios does not work. Boot log: http://ward.vandewege.net/coreboot/seabios/20090513-seabios-no-serial-debug.cap If CONFIG_DEBUG_SERIAL is set to 1, the bug persists, but sgabios works.
