The superio needs 0x87 sent twice to 0x3f0 to enable extended function (power-on strapping). Although this is already done in superio.c, it's not being done when w83977tf_early_serial.c is executed. As such, no console_init -- atleast in my case.
(Next on the agenda, check the other winbond superio chips to see if this is needed as well as I have the chip spec pdf files here as well. I noticed the other winbond chips use different addresses and values.)

sorry, should have named this with a v2_ prefix!

Don't worry, the file name doesn't matter. It _should_ be descriptive (no 'foo.patch' or similar), but otherwise it doesn't matter much. You can prepend the 'v2_', but it's not required.
