I like this utility plotting my cpu-usage aiganst my cpu-temperature. I tried running+compiling on my amd64 box using a 2.6.20 kernel. I don't know how to check for acpi support and 2.6 kernel, but I prepared a basic ebuild which works just fine for me.

I have tested this on ~amd64. Really nice application too.
Upstream still exists but there hasn't been a new release since 2005, moreover it depends on gtk2. Is there anyone still interested on maintaining this package? If not, this bug will be closed as WONTFIX in 30 days.
