Modified: trunk/LinuxBIOSv2/src/superio/winbond/w83627thf/w83627thf_early_serial.c Log: The Super I/O needs 0x87 sent twice to 0x2e (or 0x4e) to enable extended function (power-on strapping). Although this is already done in superio.c, it's not being done when w83627thf_early_serial.c is executed. As such, no console_init() without it.
