i just ran it on my box ..under stock bios (no LB for this board yet )
ubuddie probe_superio # ./probe_superio

Subject: [LinuxBIOS] [PATCH] probe_superio: add ITE support (try2)
> This adds probing for almost all recent (since 1999) ITE Super I/O chips
> to probe_superio. Not much of the configuration is dumped, however I did
> verify against all ITE datasheets (including those not available any
> more) that the probing was non-destructive.
> More information can be extracted easily, however this needs loads of
> datasheet surfing.
