I don't know what you did, but I just double-checked and my patch
applies just fine on top of 2.6.33-rc4.

Core 0 and Core 1 are reported by the digital thermal sensors that are
built into your CPU.

w83l771/temp1 is a temperature sensor integrated into the W83L771 chip,
so it basically gives you the temperature of the mainboard.

w83l771/temp2 is a remote sensor, it could be monitoring virtually
everything. The most common would be the CPU, but the difference
between temp2 and the values reported by coretemp are suspicious. Maybe
it's monitoring something else, like the GPU. You'd have to ask the
Zotac folks. Or maybe either coretemp or the W83L771's remote sensor is
horribly wrong.

It was special for you. I'll send you the bill tomorrow.



OK, just kidding. Of course I'll push the patch in the next kernel
version. In fact it's already queued [1].
