My definition of a bad chip.

I have many other driver and i2c-core reviews in the works at the
moment so it's unlikely that I will have a spare cycle anytime soon.
Someone else will have to do it.

My "bad luck" still applies. If Abit were using standard chips instead
of their own proprietary undocumented stuff, Rick would have full
hardware monitoring support for his board already. But of course if the
design of these new uGuru chips is better than the original ones,
that's still good news.
