I've been using this driver for a while now, works fine (but not perfectly... dodgy BIOS).
From /var/log/messages:
```
May 1 19:16:06 fred kernel: it8613hwm0: <Hardware monitor on ITE SuperIO> at HWM ldn 0x04 on superio0
```
I'm running stable/13 on this machine but the patch is against current (and this compile-time tested only).
